This is the first month that we are using Tri Heart Plus for heartworm prevention. We have been able to use interceptor up until now, but we ran out and the vet has not restocked yet

.
Brody and Sophia both got the Tri Heart Plus for the first time tonight about two hours ago. Brody just vomited and he never ever gets sick

. I'm going to call the vet in the AM to see if there is another heartworm preventative that they sell at their practice. Any other suggestions?? I feel so bad for Brody
