Poor Alfie is really itching badly because when we take the collar off he goes crazy and licks the incision and surrounded area aggressively.
So the collar goes back on right away.
The problem we have with him is that he can bend in a way that he can reach the incision even with his collar on and scratch it with the edge of the collar.
He can do that only when he is on the couch or carpet floor. When he is in the kitchen on a linoleum floor it is not easy for him to do that.
So from now on when we cannot supervise him he goes to the kitchen, but I'm afraid that he will find a way to tear his incision even in the kitchen - he is a smart guy

.
I wonder how long should I keep him from licking the incision - two weeks, really

.
Tomorrow we go back to work and he will be alone for 4 hours before I come home for lunch and then 2 more hours after that. And this will go on for next three days

.
I feel sorry for him but I know that there is not much I can do but be patient and hope that visit to the vet won't be necessary
Let's have a wonderful Sunday!

no happy Sunday for us.! Alfie found a way to lick his incision with the collar on even in the kitchen. The collar is to short for him. So we are watching him constantly and hoping that tomorrow he will not be as aggressive as he is today.........If he will not stop he will need a longer collar, I guess, if there are any.
