Neutering males did not appear to be associated with an overall increased risk of cancers above the rather high level of intact males. However, spaying females at 6—11 mo. The occurrence of MC in intact females was zero, but was 8 percent in females spayed at 2—8 years. For females left intact, 5 percent were reported with PYO.
UI was reported in just 1 percent of early-spayed females. The guideline for females is the same while also maintaining vigilance for the cancers which may be associated with spaying beyond 6 months, or else leaving the female intact and being vigilant for MC. The study population was 42 intact males, 82 neutered males, 45 intact females and 87 spayed females for a total of cases.
Just 2 percent of intact males were diagnosed with one or more joint disorders, but with neutering at 6—11 mo. None of the females left intact or spayed had a joint disorder. None of the intact males or females was diagnosed with any of the cancers followed. There was no evident increased occurrence of cancers in neutered males and females. There was no occurrence of MC in intact or late-spayed females. There was 1 case of PYO in intact females 2 percent.
UI was reported in only 2 percent of early-spayed females. For males, in light of a possible increase in joint disorders for those neutered at 6—11 mo. Lacking a noticeable occurrence of increased joint disorders or cancers in neutered females, those wishing to neuter should decide on the appropriate age.
The study population was 59 intact males, 74 neutered males, 37 intact females, and 65 spayed females for a total of cases. The percentage of intact males with at least one joint disorder was 4 percent and for intact females, 11 percent. Spaying females before 6 mo. The occurrence of one or more of the cancers followed was 9 percent for both intact males and intact females.
There was no occurrence of MC in females, whether left intact or neutered at any age, and a 5 percent occurrence of PYO in intact females. There was no occurrence of UI in intact or spayed females. Reflecting the increased risk of joint disorders for males, the suggested guideline for neutering males is delaying neutering until well-beyond 2 years. Lacking a significant occurrence of increased joint disorders or cancers in neutered females, those wishing to neuter should decide on the appropriate age.
The study population was intact males, 85 neutered males, 88 intact females, and spayed females for a total of cases. The occurrence of one or more of the cancers followed in intact males was 2 percent and none for females left intact.
For males, there was a significant increased risk in one or more of the cancers to 13 percent with neutering at 6—11 mo.
UI was reported in just one spayed female. The suggested guideline for neutering, given the significant risk of cancers, is holding off neutering of both sexes until beyond a year of age.
The study population was 75 intact males, 67 neutered males, 54 intact females, and 96 spayed females for a total of cases. None of the intact or neutered males or females was diagnosed with one or more joint disorders.
For females, 2 percent of intact females had one or more of the cancers and with spaying, there was no evident increase of cancers.
UI was 2 percent in early-spayed females. In light of the significant increase in cancers in males with neutering through 11 months of age, the suggested guideline for males is delaying neutering to beyond a year of age. The study population was intact males, neutered males, intact females, and spayed females, for a sample size of cases. Males and females left intact had just a 2 percent occurrence of joint disorders, with neutered males and females showing no apparent increase in this measure.
The occurrence of one or more of the cancers followed in intact males was 17 percent, and for intact females, 11 percent. The same pattern of increase in cancers was seen in spaying females with up to 20 percent of females having one or more of the cancers with spaying done before 2 years, an increase that was not significant, but with an expanded database may have been.
There was no occurrence of MC in intact females. PYO was diagnosed in 2 percent of intact females. Just 1 percent of spayed females were diagnosed with UI. Given the risk of increased cancers, the suggested guideline for both sexes is to delay neutering until beyond 2 years of age.
The study population was intact males, neutered males, 90 intact females, and spayed females for a sample of cases. The occurrence of joint disorders in intact males was 7 percent and 5 percent in intact females. The cancers followed occurred at the 6 to 7 percent level in intact males and females. There were no significant increases above this with neutering males or females. The occurrence of MC in females left intact was 1 percent and 2 percent with spaying at 2—8 years.
Lacking a significant occurrence of increased joint disorders or cancers in neutered males or females, those wishing to neuter should decide on the appropriate age, but some people may wish to be cautious in view of the possible apparent risk in joint disorders. The study population was 51 intact males, 72 neutered males, 87 intact females, and 76 spayed females, for a sample size of cases. For males and females left intact, the occurrences of one or more joint disorders were just 4 and 1 percent, respectively, and for both sexes neutering was not associated with any increase in this measure.
The occurrences of cancers in intact males were 2 percent and zero for intact females. For both sexes neutering was not associated with any increase in this measure. The occurrence of MC in females left intact was zero.
The occurrence of PYO was 2 percent in intact females. There was no occurrence of UI in spayed females. Lacking a noticeable occurrence of increased joint disorders or cancers in neutered males or females, those wishing to neuter should decide on the appropriate age.
The study population was intact males, neutered males, intact females, and spayed females for a total sample of 1, cases. For both males and females, neither those left intact, nor those neutered at any age had a noteworthy occurrence of a joint disorder. The occurrence of MC in females left intact was 1 percent, and in females neutered at 2—8 mo.
In intact females, PYO was diagnosed in 2 percent. There was no UI diagnosed in any of the spayed females. Lacking a noticeable occurrence of increased joint disorders or cancers with neutering in either sex, those wishing to neuter should decide on the appropriate age. The study population was 71 intact males, neutered males, 61 intact females, and spayed females, for a sample size of cases. The occurrence of at least one joint disorder was seen in 1 to 3 percent of the intact males and females.
Spaying females was not associated with an increase in joint disorders. The occurrence of one or more of the cancers followed was 6 percent in intact males with no increase with neutering. None of the spayed females developed UI. The suggested guideline for males is neutering beyond 6 months of age. Given the increased cancer risk for females spayed at a year of age, the suggested guideline is delaying spaying until beyond 2 years of age.
The study population was 29 intact males, 26 neutered males, 24 intact females, and 37 spayed females, for a sample size of cases. The occurrence of at least one joint disorder was seen in 7 percent of the intact males and in none of the intact females. None of the neutered males or females had a noteworthy occurrence of a joint disorder.
The occurrence of one or more of the cancers followed was 11 percent for intact males and none for the intact females. Of females spayed at 6—11 mo. Lacking a noticeable occurrence of increased joint disorders or cancers in neutered males, those wishing to neuter a male should decide on the appropriate age. The study population was 42 intact males, 78 neutered males, 50 intact females, and 70 spayed females, for a total sample size of cases.
Although these are two breeds, they vary only a little in size, so these two breeds are combined for statistical analyses and display of data.
The occurrence of at least one joint disorder in intact males was 5 percent and for intact females 6 percent. There was no significant increase in this measure in males or females with neutering. This is one of the breeds where intervertebral disc disorders are a concern, and in 3 percent of intact males and 8 percent of intact females, IDD was reported. In males neutered before 6 months, the occurrence of IDD reached 18 percent, and in females there was no increase with neutering.
The occurrence of one or more of the cancers followed was 5 percent in intact males and 6 percent in intact females. In neutered males and females, there was no evident increase in cancers. There was no diagnosis of UI in spayed females. Lacking a noticeable occurrence of increased joint disorders, IDD, or cancers with neutering females, those wishing to neuter a female should decide on the appropriate age. The study population was intact males, neutered males, 99 intact females, and spayed females, for a total sample size of cases.
Joint disorders were basically absent in males and females, left intact or neutered. This is a breed plagued by intervertebral disc disorders, and in this sample 53 percent of intact males and 38 percent of intact females were diagnosed with a form of IDD.
There was no evident increase in this measure with neutering of males or females. The study population was intact males, 91 neutered males, 53 intact females, and spayed females, for a sample size of cases. The percentage of intact males with at least one joint disorder was 2 percent and 0 percent for intact females. There was no evident increase in this measure with neutering males. For females, spaying within 11 months resulted in an increase in joint disorders of 11 percent, which did not reach significance.
The occurrence of one or more of the cancers followed for both intact males and intact females was 2 percent. In neutered males at the 1 year and 2—8 year periods, there was a non-significant increase in occurrence of cancers to 6 percent and 13 percent, respectively.
For females, there was no noteworthy increase in cancers with spaying at any time. The occurrence of MC in females left intact was 2 percent and 4 percent for those spayed at 2—8 years. There was a 7 percent occurrence of PYO in intact females.
The suggested guideline, based on fragmentary results, for males is to leave the male intact or neuter before 1 year of age to avoid the possible increased risk of cancers seen in those neutered beyond a year of age. For females, the suggested guideline, also based on limited data, given the risk of UI in early spayed females, and the possible increased risk of a joint disorder, is to consider delaying spaying until beyond 2 years of age.
The study population was 52 intact males, 57 neutered males, 37 intact females, and 66 spayed females for a total sample of cases. In males and females left intact, the occurrence of one or more joint disorders was 5 and 8 percent, respectively.
Among males and females neutered at various ages, there were no noteworthy increases in joint disorders. The cancers followed occurred in the intact males and females at a 6 percent level, and neutering at any age was not associated with any evident increase in this measure in either sex. In intact females, MC was diagnosed in 6 percent, and for those spayed at 2—8 years, 15 percent. PYO was not reported in any of the intact females.
Spaying females at 6—11 mo. For females, given the increased risk of UI in those spayed before 1 year, the suggested guideline is to delay spaying until a year of age. The study population was intact males, neutered males, intact females, and spayed females for a total of 1, cases. In males and females left intact, the occurrence of one or more joint disorders was 6 and 5 percent, respectively.
The occurrence of one or more of the cancers followed for intact males and females was 3 percent and 2 percent, respectively.
Neutering at the various ages was not associated with any appreciable increased risk in cancers followed. The occurrence of MC in intact females was 5 percent and for those spayed at 2—8 years, 6 percent. Of intact females, 3 percent were reported with PYO.
The suggested guideline for males, given the risks of joint disorders, is delaying neutering until over 2 years of age. For females, with the same joint issues as males plus the risks of UI, the suggested guideline is delaying spaying until over 2 years of age. In intact males and females, the level of occurrence of one or more joint disorders was 5 percent and 4 percent, respectively.
The occurrence of one or more of the cancers followed in intact males was a high 15 percent and for intact females 5 percent. The occurrence of MC in intact females was 1 percent and for those spayed at 2—8 years, 4 percent. No cases of UI were reported in females spayed at any age. The suggested guideline for males, based on the increased risks of joint disorders and cancers, is delaying neutering until beyond a year of age.
The suggested guideline for females, based on the increased occurrence of cancers at all spaying ages, is leaving the female intact or spaying at one year and remaining vigilant for the cancers. The study population was 90 intact males, neutered males, 69 intact females, and 91 spayed females for a total sample of cases.
This is a giant breed where one might expect a high risk of joint disorders. However, both intact males and females have low levels of joint disorders, just 1 and 2 percent, respectively. For both males and females, there was no evident increase in this measure with neutering.
The occurrence of one or more of the cancers followed in intact males was 6 percent and for intact females, 3 percent. There was no evident increase in this measure of cancers with neutering in either sex. In early-spayed females, no UI was reported.
However, given the large body size, and physiology of late musculoskeletal development, neutering well-beyond year 1 should be considered. The study population was 30 intact males, 19 neutered males, 21 intact females, and 16 spayed females for a total of 86 cases.
Even with the small number of cases, this breed was chosen for analyses because of the large body size: challenging the Great Dane for height, and where one might expect an increased risk of joint disorders.
In this sample, 7 percent of intact males and none of the intact females had a joint disorder. No joint disorders were seen in neutered males or females. With the intact males and females, the incidences of one or more cancers were 8 percent and 21 percent, respectively. There was no evident increase in cancers in neutered females above the relatively high level in intact females.
There was no occurrence of MC in intact females or those spayed late. The suggested guidelines for males given the increased occurrence of cancers around at ages 1—2 years, is neutering beyond 2 years.
However, given the large body size, and physiology of late musculoskeletal development, some may want to consider neutering females well-beyond year 1. The study population was 92 intact males, 87 neutered males, 84 intact females, and spayed females for a total sample of cases. As in other small dogs, joint disorders were rare; none of the intact males, and just 2 percent of intact females had one or more joint disorders.
Neutering was not associated with any increase in this measure in either sex. In intact males, 3 percent, and in intact females none, had one or more of the cancers followed. There was no evident increase in cancer occurrence in either sex with neutering at any age. In those spayed at 2—8 years, MC was diagnosed in 3 percent. UI was not diagnosed in any females. One or more joint disorders were reported in 6 percent of both intact males and intact females. This measure was significantly increased to 13 percent for males neutered before 6 mo.
The occurrence of cancers followed was 8 percent and 6 percent, respectively, for intact males and females. Neutering at the various ages was not associated with any evident increased risk in the cancers. The occurrence of MC in intact females was 1 percent and for those spayed at 2—8 years, 2 percent. For females left intact, 2 percent were reported with PYO.
For females, given the increased risks of joint disorders with spaying through 11 months of age, the suggested guideline is delaying spaying until beyond a year of age.
The study population was 49 intact males, 72 neutered males, 65 intact females, and 86 spayed females for a total sample of cases.
As mentioned in Appendix 1 , the Maltese and Chihuahua vie for the smallest breeds and the Great Dane and Irish Wolfhound for the largest, but all four breeds share a low predisposition to joint disorders. For the Maltese in both sexes, there was no occurrence of joint disorders in either those left intact or neutered. Virtually the same picture emerges with cancers, with only one of 64 intact females being diagnosed with a cancer.
There was no occurrence of MC in the intact females and only one case among the 19 females spayed at 2—8 years. PYO was seen in none of the intact females.
