He's walking, except not so great on the hardwoods or the kitchen flooring... once he's down on them, it's hard for him to get up. He's doing great on the carpet and out in the yard on the grass. His balance is much better.
His "accidents" are getting fewer and more far in between. He's making it to the paper or barking to go out when its time, so my carpet is grateful, and I won't have to take out a loan for the purchase of more paper towels, but it's definitely carpet cleaning time. Oh, how wise and optimistic was I to put in $2,000 of berber carpeting with 16 and 14 year old dogs.
