Results: 2018 General Health Survey
Endocrinology
Conditions listed in the Endocrinology category were reported in 4.2% (49) of 1,171 surveys completed across all breeds/varieties surveyed.
Considering the entire population surveyed:
Considering the entire population surveyed:
- Incidence of endocrine disease was not consistent across all breeds/varieties examined, with North American rates at 9.7% for Standard Manchester Terriers and 6.9% for Toy Manchesters compared to just 1.5% in Manchester Terriers (UK/FCI) and 1.3% in English Toy Terriers.
- The most common disorder reported was hypothyroid, which was seen in 24 dogs total, representing 2% of the overall population. This disease was most common in Standard Manchester Terriers at a rate of 5.4% compared to 2.6% of Toy Manchesters and 1% or less in Manchester Terriers and ETTs.
- In 2002, the rate of hypothyroid reported in the combined Toy and Standard Manchester Terrier population was 2.6%. In 2018, the rate among Toy Manchesters was also 2.6% but rose to 5.4% among Standard Manchesters.
- Cushing’s Disease and Diabetes Mellitus were the second and third most common issues reported, affecting less than 1% of the total population.
Conditions
The following conditions are referenced below in the analysis for this section. The explanation for each disease/condition provided in the survey is included for reference:
- Addison's Disease (lower than normal production of hormones, such as cortisol, by the adrenal glands)
- Cushing's Disease (excess cortisol levels caused by a pituitary tumor)
- Diabetes Insipidus ("water diabetes" - inability to regulate water metabolism, characterized by excessive thirst and increased/dilute urine)
- Diabetes Mellitus ("sugar diabetes" - excessive sugar in the blood and urine due to inability to use insulin)
- Hyperthyroidism (increased activity of the thyroid gland)
- Hyperparathyroidism (increased activity of the parathyroid glands)
- Hypothyroidism (deficient activity of the thyroid gland)
- Insulinoma (insulin producing tumor)
Toy Manchester Terriers
The most common conditions affecting Toy Manchester Terriers in the Endocrinology category were Hypothyroid, which was reported in 8 (2.6%) Toy Manchesters, and Cushing’s Disease, which was reported in 4 (1.3%) Toy Manchesters. Additional conditions reported included two cases of Diabetes Mellitus (1%) and one case each of Diabetes Insipidus, Hyperthyroid and Hyperparathyroid (0.3%). An additional case of diabetes was identified as cause of death in a 12-year-old dog, however the type was not indicated in the body of the survey.
In the ‘other’ section, one owner identified a suspected but unconfirmed case of Cushing’s Disease; a dog with high autoimmune markers that may have pointed to Addison’s Disease; and a dog with short-term diabetes insipidus and incontinence resulting from a reaction to oral steroids.
The rate of hypothyroid in Toy Manchesters reported in the 2018 general health survey is unchanged as compared to the rate reported in the 2002 general health survey (which combined Toy and Standard Manchesters together).
Associated Deaths
Three Toy Manchesters died from conditions listed in the Endocrinology section, with two dogs dying of Diabetes (one diabetes mellitus and the other not identified) both at age 12. One Toy Manchester also died of Hyperparathyroid at age 12.

Standard Manchester Terriers
The most common condition affecting Standard Manchester Terriers in the Endocrinology category was Hypothyroid, which was reported in 10 (5.4%) Standard Manchesters and Cushing’s Disease, which was reported in 5 (2.15%)dogs. Additional conditions reported included three cases of Diabetes Mellitus (1.6%), two cases of Hyperthyroid (1.1%), and one case of Addison’s Disease (0.5%).
In the ‘other’ section, one owner explained that Addison’s Disease in his/her dog resulted from a reaction to treatment of Cushing’s Disease. Another owner explained that Cushing’s Disease in his/her dog was caused by tumors on the adrenal gland and resolved once the tumors were removed. And a third owner indicated that their dog’s symptoms have prompted their veterinarian to test for Cushing’s Disease several times but the results so far have been negative.
Associated Deaths
Three Standard Manchesters died from conditions listed in the Endocrinology section, with one dog dying of Cushing’s Disease at age 17; one dying of “Cushing’s Disease/Addison’s Disease/Old Age” at age 15; and, one Standard Manchester dying of Pancreatitis/Diabetes at age 11.
