Background:
The English Cocker Spaniel Club of America requested a general health survey
for English Cocker Spaniels. The purpose was to find possible emerging
breed-related health problems, so that concerns and breed problems can be
addressed. Previous surveys were used as a basis for the current survey.
Methods:
The survey was mailed to all members of the English Cocker Spaniel Club
of America between December 31, 2001 and January 10, 2002 requesting responses
by February 14, 2002. It was noted that if a member did not want to participate
or no longer had an English Cocker, then they should return the blank survey.
Postcard reminders were sent out in June and October 2002. Another copy
of the survey was sent out in October 2003. New addresses on the mailing
list required an additional postcard reminder in March 2004.
Answers from the surveys were compiled into excel spreadsheets under each
survey identification number. Then data was sorted into tables for easier
analysis. In most cases, variables (i.e. age, color, and sex) were specifically
noted in the tables. It should be made clear that ages are in years, except
when noted.
Results:
There were 487 English Cocker Spaniel owners and members of the club who
responded; 287 of these were breeders. Originally, 812 members were sent
surveys; however, 67 of these no longer had dogs, had died, were not members,
or had bad addresses. Sixteen blank forms were returned, and there were
487 responses, therefore we had a 65% response rate. Possible reasons as
to why the rest did not reply cannot be certain. Reasons could include:
1) too time consuming; 2) too many dogs to include; 3) too many health problems;
4) very few or no health problems; 5) have not recently owned English Cocker
Spaniels; 6) some other unknown reason. The higher the response rate, then
the more accurate and conclusive the data. The survey did include a total
of 3,537 English Cocker Spaniels. The top problems in the dogs were: bite
problems (7.63%), skin allergies (4.16%), shyness (3.53%), cataracts (3.31%),
deafness (2.86%), aggression towards other dogs (2.8%), and benign tumors
(2.52%).
The majority of the dogs in the survey were parti-colored. Fifty-nine
percent of the respondents were breeders who bred an average of one litter
per year, with an average of four puppies per litter. The most common reproductive
problems in female dogs were irregular heat cycles and difficulty whelping,
this accounted for 46% of the female reproductive problems. In male dogs
cryptorchidism was the most common, accounting for 60% of the male reproductive
problems. Leading causes of death in the dogs were old age and cancer.
Blood disorders were extremely rare. No dogs surveyed had been diagnosed
with hemophilia. Bone and joint problems were extremely rare. Hip dysplasia
occurred in less than 2% of the dogs and only 1% of the dogs had any type
of disk problems. Eighty-three dogs had some form of cancer and eighty-nine
dogs had benign tumors. Together this accounts for only 5% of the dogs.
Cardiovascular diseases were low, with less than 2% of the dogs having heart
murmurs. Allergies affected approximately 4% of the dogs (147 cases), with
15 cases being affected by Demodex.
Forty-three percent of the dogs have been BAER tested. Almost 3% of the
dogs had deafness in either one or both ears. From the dogs that produced
deaf puppies, 44 puppies had incomplete masks and 12 had blue eyes. Approximately
8% of the dogs surveyed had chronic ear infections. Hypothyroidism was
the most common endocrine disease, but only affecting just over 1% of the
dogs.
Cataracts occurred in 3% of the dogs; and slightly less than 1% of the
dogs had blue eyes. Gastrointestinal problems only affected approximately
2% of the dogs. Sixty-eight dogs (2%) suffered from seizures, while only
thirteen were maintained on anticonvulsants. Eight percent of the dogs
had bite problems, with half of these having an undershot mouth. Six percent
had lip fold infections.
One percent of the dogs were aggressive to people, while two percent were
aggressive to other dogs. Shyness affected 4% of the dogs. Urinary and
kidney problems affected 3% of the dogs; one percent had bladder crystals.
Nineteen percent of owners with dogs had experienced vaccine reactions.
Pica was a problem that 37% of owners had encountered. The OptiGen DNA
marker test for prcd had been used by 95% of dog owners. Eighty-six percent
of owners felt that it is important for the ECSCA to maintain a special account
for health research, with almost 60% of the respondents already have or plan
to contribute to the account. Eighty-two percent felt that health concerns
were very important.
