If Flea Collar Irritates, Try Sprays, Dips

Q: In the past two weeks, both of my cats have started to get a lot of fleas. I used to use flea collars on them, but the female developed a severe rash around the neck. Is it safe to use other products?

Suzanne Grimes, Seal Beach

A: Flea control requires treatment of the pets and their home environment. Treating the house and yard is important and requires repeated treatments at two- to three-week intervals. You should be able to use a flea spray on your cats but you might want to first spray a small area on the abdomen of the female and see if there is any local skin reaction. Powders can be effective but must be used with care. If you decide to use a dip, make sure that it is safe for use on cats and that you carefully follow directions.

Get your veterinarian’s advice on which products will be effective yet safe. Flea control takes determined follow-up treatments of the home area and pets.

Q: I have heard many things about Lyme disease in people and how they can get it from ticks. Since I have two dogs and frequently take them camping with me, is it possible that dogs can catch this disease too?

Myles Beale, Anaheim Hills

A: Lyme disease is often spread by the deer tick. It is definitely possible for your dogs to contract the disease from infected ticks. The disease is difficult to diagnose because it mimics other illnesses and the small tick is often not found.

Lyme disease will cause a fever, weakness or lethargy, and arthritic disease as well as a potential for kidney problems in dogs. Unlike humans, dogs do not often show a red rash before the other signs become apparent. The organism is called Borellia burgdorferi and is carried in the bloodstream. Prevention includes the use of flea and tick sprays or dips after each trip to a wooded area. Careful examination of your dogs may locate any ticks that might be taking a blood meal. If you suspect a problem, contact your veterinarian.
