I have a border collie lab mix, male, 3 years old, fixed. We believe he is reacting to the flea/tick drops, but are not quite sure. Against my better judgement, I purchased some Hartz drops a few months ago as the Advantage didn't protect against ticks and we not live in the woods with lots of ticks.
Anyway, the first exposure was in May with no problems other than gumming up his beautiful coat. The next exposure was a little late, coming about 6 weeks later. Ever since that time, he has been losing hair at an alarming rate (with his thick coat you don't notice it on him, but we have it all over the house!) he has had some foamy vomit ona few occasions (about a week or so ago, seems to have ceased now), and he has been itching frequently.
We have scoured him from nose to tail and have not found a single flea or tick. He is still jovial and active, seems to be eating well, coat is still shiny and soft. We did some reading at it seems like this is most likely a reaction to the drops, but I wanted to make sure. He seems to be triggering his happy spot no matter where he scratches himself, which is very odd for him.
Thanks. I have an appt scheduled with the vet, but it never hurts to ask for another opinion, right?
