Moose is looking good!
I don't know if the vet said anything about icing his incisions but i think it helps the itchies. we'd recommend icing each incision 4 times a day for 10 minutes each. it helps with the swelling and redness, plus it numbs the area so he can't feel the itchies.
If you have an ice pack, wrap it in a paper towel and hold that over the incision, or you can make plain ice popsicles and use that. we'd do that with paper bathroom cups and tongue depressors. icing can't hurt and it might help. however if he struggles while you're doing it then don't bother, you wouldn't want to make it worse. Most dogs tolerate it just fine.
