If Flea Collar Causes Reaction in Your Pet

DEAR PAW’S CORNER: I’m worried by recent reports that a certain brand of flea collar has been making dogs sick, and many have died. I live in an area where fleas and ticks are rampant, and flea collars are essential for my two pups. What can I do if they have a reaction to a new collar? -- Jane in South Carolina

DEAR JANE: It’s understandable that you’re worried. At the moment, the issues with the flea collar in question, Seresto, are being reviewed by the EPA, and no recall or warning has been issued.

Flea collars are widely available from different manufacturers. They’re a popular choice because of the ease of use and affordability. However, any of them can cause side effects, and it’s important to monitor your pet for them. A common one is a skin reaction directly underneath the collar shortly after it’s put on for the first time. Your dog may scratch at the area; you may see reddening of the skin. Some reactions include hair loss around the collar.

The itching is usually temporary. Consult your pet’s veterinarian if you see redness or hair loss, if the scratching and whining continues, or if your dog shows other signs of distress. If your pet is lethargic, drooling, vomiting or behaving strangely right after a new collar is put on, contact the vet immediately; it likely needs emergency treatment.

To prevent these and other side effects, make sure to purchase the correct collar for your dog’s size and age. Putting a collar designed for a 100-pound dog onto a 15-pound dog can cause dangerous side effects because a small dog’s body just can’t process that much flea treatment.
