Hello! Welcome! I am so happy for you to hear that your pup is doing so well. Parvo is my most dreaded diagnosis as it always hits the very young and often it is either too expensive for people to treat it too severe for dogs to survive.
I would place the ecollar and make sure he can’t lick the area. And I would also keep it cleans and dry. I usually don’t wrap it because it can be too tight and cause really bad problems for rhe leg and cover up a wound I would rather have people observing daily. Covered up leans you can’t see it and I want to to be monitoring it.
If it worsens call your vet and have it looked at asap.
Good luck
Hello
I’m sorry for the delay. If you would like a consult I would be happy to meet you and discuss options. Please call the clinic and ask for an appointment. It is the best place to start.
