Awww ((hugs)) Don’t feel like a bad Mommy- sometimes things just happen. It is very hard to keep tabs in their mouth. Plus the Vet should have said something to you.. All you can do moving forward is look in his mouth often, make sure all is well. Try not to get too upset over it, things happen. What matters is Scooter has a clean mouth now.. I will be sending good thoughts to Scooter, hope he is back up to his normal self soon!!
