I purchased a teacup maltipoo from Tiny Cutie puppies. The description was for a 7 month old female weighing at 1.7lbs. And will grow an estimate 3-4lbs full grown.
Once I received my puppy, I took her to the vet and they advised that my puppy wasn’t even close to being 7 month due to the fact that she still has her baby teeth. They estimate her age somewhere between 3-4 months. I took her to a second vet and they also agree that my puppy is 3-4 months. I texted tiny cutie puppies and have not heard back from them.
I also feel the vet they use to give us a certificate bill of health is greatly questionable. They should have caught that.
