Hello, Thank-You for taking the time to read this.. How do I sedate my 70 lb. dog so I can change his bandage every 2 days. I took him to the vet he has an open wound on his right side elbow for about 6 months or so. It started getting worst to where he started limping. I knew I didn't have the money to take him to the vet but I was now forced to. I'm sorry for waiting so long. I don't get paid much, I work 3 days a week and such a small budget. So with what little...
