dental issues

Hi all. I have a 3 year old golden retriever and noticed something strange when we were playing earlier. I accidentally grabbed him playing earlier and felt the roof of his mouth. Near his front teeth, the roof of his mouth is pretty squishy and soft, is this normal? I’ve seen some comments...

My 4 yr-old golden seems to have an issue - her lower middle teeth appear to have dropped forward and are disappearing into her gums (see image). She doesn't play tug-of-war or chew rocks etc. so not sure what might be causing this or how serious it may be (or not?). Our vet wants to do dental...
