dogs teeth

Question
My son has a 2 year old Australian Shepherd. He said the dog has lost 3 teeth and asked me if this is normal. Can you help!
Thanks  

Answer
It is normal for younger puppies to lose teeth, however two is a bit old. A health matter could be the underlying problem so I would definitly consult with your veterinarian. I am very sorry for the delay in answering your question. I had some things going on around here. I hope I helped. Have a great day.
