Sophie appears to have some sort of tooth problem. Not long after we got her (in July) we noticed she had sensitive teeth. She could chew her bones and play with her toys but sometimes if we gave her a very hard bone she would whine a little while trying to chew it. As time went on, she seems to have gotten worse...we would give her a bone and she would carry it around, crying. And even larger treats she had problems with. We went to the vet and everything was fine....I figured it was just teething. But now it's gotten really bad. Sometimes she won't eat her food unless I get it moist and just ten minutes ago I gave her a treat and she walked around with it, whining...and at one point she was in so much pain that she urinated on the carpet a little bit

. Could it just be teething? She's 7 months old...Should I maybe get a second opinion? I'm really worried
