Puppy Teething
Puppies start losing baby teeth at about 12 weeks and have all 42 adult teeth by 6 to 7 months. Chewing and tiny spots of blood are normal.
What to do
- 3 to 6 weeks old: the baby teeth come in, usually before your puppy comes home.
- From about 12 weeks: baby teeth start to fall out as the adult teeth push through. Most puppies swallow them harmlessly.
- By 6 to 7 months: all 42 adult teeth should be in, with no baby teeth left.
- Give chews that bend a little or that you can dent with a fingernail. A toy chilled in the freezer can soothe sore gums.
- Supervise chewing, rotate a few safe toys, and keep shoes, clothes and children's toys out of reach.
- Take away any toy that's breaking apart or missing pieces.
- Look in your puppy's mouth each week. If a baby tooth is still there beside its adult tooth, see your vet.
Don't
- Don't give bones, antlers, hard nylon chews, rawhide or pig ears. Hard chews can break teeth.
- Don't use human toothpaste on your puppy.
When to call your vet
- A baby tooth is still there next to its adult tooth
- A broken tooth
- More than a few spots of blood
- Baby teeth still in place after about 7 months
Why
Chewing seems to ease teething discomfort, so puppies chew nearly everything. Very hard chews can break both baby and adult teeth.
