I just noticed that my vet had given me the 50-100 lb dose of sentinel for my 26 pound whippet. i have given her three doses(one/month) over the last three months before I noticed this. Is there a problem for my dog at this time? I plan to go exchange the remaining three tablets for the 25-50 lb dose.
Sentinal is very safe. I would not be terribly concerned but i would get the proper dose. Vetcare
