All canines, including Yorkies, should be on some type of protection against fleas. If you’re not sure about a topical ointment, a pill, or a flea collar then give your veterinarian a call. Flea collars are just one of many treatment options for preventing fleas. Most flea collars are simple to use and last anywhere between 3 to 8 months. Talk to your vet to find out if a flea collar is right for your Yorkie. Also ask your vet for suggestions on what brand, size, and type of flea collar to buy and whether or not a collar can be used in addition to a topical treatment. Flea collars release a defense mechanism on the neck and shoulder area of a dog. This drives the fleas to the tail where they die and fall off. Your vet Crown Point, IN can offer additional suggestions.
