@tarayummy If he will let you you can apply a compress to the area. Cool helps the swelling with the first 12-24 hours and a warm compress helps with fluid build-up in the area. Whichever he will tolerate will be ok. The next day or 2 will be the most uncomfortable for him.
@tarayummy I've been a vet tech for 13 years, if you have any questions just DM me.
3 big things: 1. Do not let him lick the suture site! 2. Do not let him jump or play. Outside to potty then back inside. 3. Keep him calm, no activity for at least 7 days. Some have reactions to the suture
