Q: Our family wants a Labrador Retriever puppy but we have learned that the breed is predisposed to hip dysplasia.How do we find a puppy with a lower risk of developing the disease?

A: First, look for a reputable breeder; it is not advisable to pick a puppy from the newspaper or from in front of the grocery store, no matter how cute it is. Try asking a veternary staff member if they have any recommendations, attending local dog shows, or researching breed registries or sites on the internet. Be sure both of the puppy's parents have been screened for hip dysplasia (done with x-rays) and ask the breeder for their OFA (orthopedic foundation for animals) rating - this rating should be "good" or "excellent" for both the mother and the father. Although this does not guarantee that your puppy will be dysplasia-free, it certainly helps lower its risk. Hip dysplasia is known to be heritable, as are several other orthopedic conditions. Many breeders are routinely screening for elbow dysplasia as well. The more information you can gather before purchasing your puppy, the better your chances of avoiding sometimes-devastating consequences of a bad breeding.

Q. My indoor cat's eyes appear bloodshot and dry. Can cats get "dry eye" like humans?

A. "Dry eye" or KCS (keratoconjunctivitis sicca)is uncommon in cats, but possible. Other more likely explanations for your cat's ocular problem are upper irritation (rubbing or environmental irritants). Because problems such as glaucoma or systemic disease can manifest similarly, having the problem assessed by your veterinarian is very important - and it should be done quickly, as procrastination may lead to permanent ocular damage. Tests for intraocular pressure, corneal defects, and tear production may be recommended if the cause is not immediately apparent. Treatment recommendations will depend entirely on the cause.
