a few days ago i found a tick on my dog and took her to the vet to have it removed. i was told it is not the type that causes lyme disease. after that i started her on flea and tick medicine. since then she has had a poor appetite and has been very lethargic which is usual for her , she is a siberian husky and normally very hyper. what could be going on that would make her act this way? she does have a vet appointment in a few weeks should i move it up?
