I know everyone is mentioning low doses of benadryl but dogs metabolize much different than ppl. I have a 75 # basset that was prescribed 150 mg of benadryl a day. And it didn’t phase him. Don’t be shocked at the dose if you vet recommends that for the dog.
Also, rabies shots are 1 for the first year, then one every three years.
Going forward you may need to med dog before getting vaccines.
Yea I kinda learned the hard way about their absorption rate. Years ago I had a big black Lab that found a bottle of Xanax I dropped in the yard. I estimated he ate about 10-15 mg. He was pretty laid back for a few hours LOL. My now ex-son in law worked for a Vet and called him and his boss laughed and said just watch him a few hours most of it won't absorb.
