IMO the heartworm prevention's good far outweighs the risk of the maybe side affects. If you ever have a dog that gets heartworms you will understand. It is not pretty and it is an long and expensive treatment to get rid of them, all the while not knowing if the dog will die. All it takes is one mosquito and here in the south even out winters are warm enough for fleas and mosquitoes. I use the frontline plus on my chi as well as the other animals. Sheila
_____ From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of sylviajeankinney Sent: Tuesday, December 12, 2006 10:38 AM To: [email protected] Subject: [Chihuahuas] Heart Worm Prevention Hi Everyone, We have a 5 lb 4.5 month old long hair chihuahua puppy named Teddy. He is the love of our life. Yesterday I took him to the vet for the first time. He got his rabies shot as he had had the other vaccines with the breeder. The vet also said to start him on heart worm prevention. I bought the one year's suppy of Interceptor but after reading information on the internet I am afraid to give it to him. The possible side effects sound scary. We spend half the year in Florida and the other half in Washington State. What do you all do for heartworm prevention? Also what about flea prevention? My puppy does not have fleas but we walk him outdoors so he may get them at some point. Thanks, Jean
