I wanted to return and give an update. The past two weeks were a rollercoaster. Ed did fairly well with recovery from his left front leg amputation. I kept him crated a lot so my little kids wouldn’t knock him over and to keep him from jumping around too much. He wasn’t drinking much water even if I added chicken broth. He has an issue with one of his eyes which appears to be an ulcer. He also has two absesses under his chin. The vet was surprised these things did not clear up with the antibiotics he’s been on. His moral was low and I started to think we made the wrong decision. 
His stitches were removed at 14 days post op. His eye issue tested negative for any cancer cells, we are waiting to hear on the chin infection. Trying different antibiotics. These concerns mean we have to postpone chemo treatment. 
All that being said, Ed now has free reign in the house again. He has mastered the stairs. He chases chipmunks. He goes for short walks. He plays tag with the kids in the yard. He lounges in the sun. He once again sings to the harmonica. His feeding schedule is back on track and I think the increase in excercise has made him drink his water regularly. The future is unknown, we don’t know how much time he will have but these times are beautiful. Ed is back and having fun.
