Thank you all so much! Kelly, I have yews, but I thought it was Juniper. I don't think he ate it, but I could be wrong. Donna, Bentley wasn't on any medicine, just cosequine and glucosamine, but he's been on that.
I got Pepcid AC in him as well as the med for vomiting. He FINALLY started drinking water around 5 pm. He's still avoiding food, but will eat oyster crackers and his mama's dog cookies (pumpkin)
If he's not eating by tomorrow am, I'm taking him back to the vet and having his blood checked. I appreciate your advice and your kind words.
