I feel so bad for him! DH took him out to use the bathroom and met a neighbor's dog (they were outside & he was tied up on a long lead). Unfortunately, I wasn't there so I don't know all the details, but long story short DH thought it was a harmless occurrance and they came inside. About an hour later I heard him licking and I looked down and there's a hole in his side the size of a 1/2 dollar!!!! We rushed him to the emergency vet (which is maybe a 1.5 blocks away) and they ended up giving him stitches and 4(!) drainage tubes. [

] Unfortunately he has to have the tubs in for 3-5 days and the stitches will come out 7-10.
While he was in surgery we came home and talked to the owner. She felt sooooo bad. We got her dog's shot info and she said she's willing to pay for the bill. She was so nice. She said this is the first time that her dog even acted aggressive towards another dog. The dog that bit Copper (his name is Dozer) knew he was in trouble as he kept sulking and not making any eye contact.
My concerns are the drainage tubes. What am I to be watchful of? He's been laying on that side (probably feels no pain right now) and when he stands up there's blood on the carpet. We clean it up right away, but are we to expect this the whole time? We've been trying to get him to lay on his other side but I'm afraid that he's going to lay on the bad side while we're sleeping. Any advise as to what to expect for the next week??
ETA: He also has to wear the ecollar 24/7. Any suggestions as to how to feed him with the collar on?
