My dog was neutered. He’s a 2 year old Maltipoo mix We are on day four I’ve been consistent with his pain medicine and sedatives. He rest most of the day. He’s been pooping/peeing normal, eating and drinking his water but today, I noticed it was a little redness around the site. I will be calling the vet tomorrow morning but is this something I should worry about tonight?
