Irish Wolfhound Pedigree Breed Health Survey

Transcription

1 Irish Wolfhound Pedigree Breed Health Survey Forms were received representing 74 living dogs & 32 deceased dogs. Mortality results A total of 32 deaths were reported, representing 0.57% of all deaths reported in the Pedigree Breed Health survey. The median age for the Irish Wolfhound was 6.5 years (Figure 1). Table 1 shows the causes of death for the breed. Age at death is presented for the most common causes in Figure 2. Table 1 The causes of death/reasons for euthanasia (N = 32 deceased dogs). Cause of death Number of cases Proportion (%) Cardiomyopathy Bone tumour Cancer - unspecified Cardiac heart Failure Old Age combinations Kidney Failure Meningitis Unknown Arthritis Gastric dilation-volvulus syndrome (GDV)/Bloat Kidney disease Leukemia cancer of the blood Old Age Renal Dysplasia Road Traffic Accident Surgical complications

4 Morbidity results The 74 live Irish Wolfhounds represented 0.17% of total dogs in the survey. The median age of live dogs for the breed was 3 years (Table 2). Of the 74 Irish Wolfhounds which the survey covers, 43 had reported no conditions and 31 reported affected by at least one condition (min = 1 condition(s), max = 8 conditions), giving a total of 73 incidents of conditions. The gender, neuter status and age of neutering summary statistics for Irish Wolfhounds are shown in Table 3. There were 55 dogs with responses for Body Condition displayed in Table 4. The median age the dogs were first affected by a condition was years (min = years, max= years, Figure 3). The ages for the most common conditions is displayed in Figure 4. Table 5 shows the frequency of occurrence of all reported disease conditions for the Irish Wolfhound.

The most commonly reported disease condition in live dogs was skin (cutaneous) cyst. The most commonly reported cause of death was cardiomyopathy.
