In the future if this happens but its a lot more chocolate.....You can induce vomiting but giving them 1/2 tspn of Peroxide....the kind ya keep around for boo boo's......but this has to be done within 45 minutes of eating the chocolate.
I know this because Diggy ate equivalent of 3 hersey kisses. I called vet immediately and this is the instructions they gave me
Good to know just encase they eat something they shouldnt. I would always consult vet first but when thats not possible its an option. There are lots of posts on here about when and when not to ude peroxide too.
Glad he is okay
