age of my pet

Question
i live in india and purchased this dog from a dog shop. they gave us the dog saying he was one and a half month old however he was still teething and would wobble on his feet. he also had parvo. he is now fine but the vet has given me papers claiming he is 6 mths old. The doctor however says that the pup can not be more than 3 months. His milk teeth are being replaced by permanant teeth now and he is about 12kg wt. can you tell me what is my pup's age, likely?

Answer
Hi anu. I am and indian too. But i live in the U.S. First of all, the puppy shouldn't be taken away from its mother before 9 weeks of age. But, it seems to me that the seller lied to you about the age. A one month puppy doesnt weigh that much. And permanent teeth come at around 5months old. Make sure you take care of your dog well. your pet is your son now. Don't neglect him.
