I have 2 puppies and the bitch has had 2 teeth come out. Im not sure if they have been knocked out as she plays with the other puppy or im not sure?? the first one had split and i was going to take her to the vet but when i got up in the morning it had gone! The second one has half come out and is bent over horizontally. She doesnt seem in any discomfort, but i just wanted to know if this is normal? she is 15 weeks old.

None of the other puppies teeth have come out yet?

Any help/info would greatly be received.

LOL
This is totally normal :)  from now on you will notice them losing teeth regularly and chewing more, they may go off their food too if its hard to crunch and their gums hurt, you could try soaking it if this happens ;)  Often you can see where the next teeth are going to fall out as the gum will be a little swollen and pinker.

Raw Bones (bigger the better) will help the teeth fall out and satisfy the need to chew.

Hope this helps
