Lara, I felt so bad reading about poor Blu (and you). What a horrible scare. Thank goodness you heard him and got him to the vet in time!
Here's yet another tip on getting a pill down. Wrap it firmly into a glob of cheese, like American cheese. He should eat it right up. This was a tip from my dog's vet.
There are even tasty nuggets of some kind sold just for inserting dog's pills. My vet sells them but he said even just the cheese would work.
I hope poor baby Blu feels better asap.
BTW, I bet your place looks beautiful with all that sprucing up, and those black metal fences are so nice looking. But copperheads? I never even saw one, omg I would freakout.
Funny thing about dogs....now matter how large the enclosure, the dog will always be at the furthest point.
