Wow, what a roller coaster ride these last 4 days have been. Cocoa is 99% improved from Thursday night. He improved dramatically over the weekend. He slept A LOT, and each time he woke up he was doing better. This morning he bounded down the flight of stairs and raced outside to the yard to do his business. Over the weekend I massaged his body and legs twice a day and helped him drink enough water (he wouldn't drink any water Friday, so I sprayed water on his fur and he licked it off, by Saturday morning he was drinking out of a shallow bowl and Sunday back to normal). Each time after I massaged his legs he would stretch them. It seemed to really help him by getting the blood moving again.

The vet didn't tell me about vitamin K, she just said to let him rest (which he did a lot of!) and to get him to drink as much water as he could.

I hope my frightening experience can help others, either by understanding the potency of tea tree oil, or, God forbid, if someone else finds themselves in a similar situation.

Thanks for the support I got on this site too. You people are golden!
