How do you determine if your dog needs a dental exam? My dog is over 10 years old and has always had bad teeth. He is a Yorkshire terrier mix. I knew he would need several teeth extracted but we were not advised that he must have this done by x date. It’s been about 6 months. He has now had two teeth fall out and has another big tooth loose. I do not mind paying for a vet visit if necessary but I wasn’t sure if this was simply part of old age. Should we switch from dry food to wet food? He has a little redness in his mouth, no swelling, no signs of pain.
