 |  |  |  | Wow ... a few issues going here, in this thread.
First, the Heartgard. Heartgard is Ivermectin, which I've never had any problems with, in either dogs or horses, but Ginger's right, I've heard that shelties and collies may have allergic reactions to it.
I would be more likely to think that the Frontline caused your problem. I use Frontline with no problem on Sterling, but this type of flea treatment is absorbed into your dog's fatty tissues, so a reaction might not occur until a day or two later (when enough has accumulated into their fatty tissues).
Either way, I wouldn't administer both medications on the same day (not that you did, but just in case).
Regarding vaccinations ... Sterling is highly sensitive to vaccines too. Your vet can do a titer test (I may have spelled that wrong). Anyway, your vet takes a blood sample, and the lab checks it to see your dog's levels of antibodies for the disease/s in question. If the antibody levels are high enough, your dog doesn't need his/her booster that year. If not, you go ahead and get the shots. Just a thought ... and it works well for us. |  |  |  |  |
