I estimated that he ate 3 -4 pills. This was well above fatal and would shut down his kidneys if they didn't counter act it with other medication. Logger spent 56 hours in the hospital. He had an IV drip and a catheter (hopefully he will remember that before chews on something). The Vet said he was a rascal. He was barking non-stop. They were afraid he would rip his catheter out, so he had to be sedated.
We picked him up this morning and he seems to back to his old self (minus his front leg where they shaved his front leg for the IV!). He has become the most expensive pet we have ever had! But he's worth it.
