Thanks, Heidi.

I forgot to mention he threw up all his breakfast. This doesn't happen often any more, but when the vet was examining him for the possible UTI he showed me which of Cole's teeth had FORL on them.
One may be able to be burred down, but there are at least 3 bicuspids on the other side lower jaw that will have to go.

The vet suggested that Cole is swallowing his kibble mostly whole to avoid the pain.

Cole's oncologist doesn't like the idea of Cole having surgery (dental). With him being on chemo his immune system is compromised.

However, I'll try to see what we can do. Cole does not deserve pain after all he's been through.
