I have used capstar on my girls, and they are 3.2 and 3.8lbs. I would call the company and ask them if it is a common side effect(I know that comfortis will cause vomiting)--it could be that your baby is allergic. Usually you pair capstar with another 30 day treatment, since capstar is only good for 24 hours. Dawn will strip the oils out of the skin and haircoat--there are good flea shampoos that are ph balanced for dogs, I like mycodex or adams(I've seen this at wal-mart, it used to only be available thru a vet). My boss raises yorkies, anytime the puppies need a bath-this is what we use(I'm talking maybe 4 week old pups and older), and we never had a reaction. Good luck, hope your baby is feeling better soon. |
