#2 Problems With Their Teeth
Loss of appetite is frequently brought on by dental problems. The first thing you can do is check your dog’s mouth for things that might be caught in their gums or teeth. The same as you, if your dog has a toothache, it may not feel like eating.
If you see any of the following, make sure to contact your veterinarian right away: a bad odor, any loose teeth, or a lot of tartar buildup.
Naturally, the best cure is prevention. Don’t forget to give your dog a routine dental brushing and to take them to the veterinarian at least once per year for a checkup.
