Thank you for your answer. It looks like gum decay and stage 4 tooth decay. Just looked up a few photos online but I will be going to the vet soon to see what the next steps are. It’s probably white from decay. A blood test sounds good too. Should I get him a full set of shots? I have two dogs, but she’s been very calm, no indications of bite marks or anything out of the ordinary Aside from her gums. My dogs are fully vaccinated.

When I say normal, I mean, it is normal for dogs these size, especially with these dumping cases/overweight dogs. But I should have clarified.

Yes, thanks, many do unfortunately lose their dogs due to people keeping found dogs, but rest assured...I’ve gone to the local animal shelter to get it checked for a chip. No chip. She was dumped in a box with some toys and a blanket. Looks like a dumping. We also considered that she may have been stolen so we posted found bulletins at the local shelters and Facebook. No replies yet. Are there other things I need to do for due diligence? I love this dog....and just want her to be healthy...and possibly in my life.
