The Problem is that MyNextPuppy.com is a Puppy Mill. They sell sick puppies. They put 2-3 puppies in one cage. They do not feed the puppies the amount they should. They charge 3-5 times the amount they should. They also sell dogs that are Food aggression. Here is a experience a person had with this company. 

Do not buy your dog from here!!!! We paid 7900 for our Rottweiler who was 19weeks old. Day 4 the dog is vomiting not eating and looks depressed. We take her to the vet ASAP they diagnosed her with yeast ear infection, PARVOVIRUS and Anemia. The vet stated she needed to go the hospital right away before it gets worst. The dog needs to be treated with IV fluids and antibiotics…..We send her off to hospital. she was so sick needing ICU care her hospital bill would have been 8k to 10k unfortunately we had to return the dog back to the pet store so they can finish paying the bills!!! We are out 3k because of this place sold us a sick dog!!!!!!! Read read read the contract don’t listen to the workers they lie!!!!!returning the dog means the treatment you started u have to pay for it….they only return ur deposit and cancel contract. you take a chance of buying a sick dog that they sell you and being stuck with a bill that wasn’t your fault ! The worst day ever is when we had to make the decision to return the dog after falling in love. My next puppy ruined this dog life!!and ours!! We are broken.  -Here is another one-

This place is by all means a scam and a puppy mill. They don't tell you the price on-site, and they have other people post lower prices referencing their store (which they then refer to as 'scammers', which makes absolutely no sense...) and when you walk into the store, boom, you're getting 10-20x the price you originally saw, and only tell you after you play with the dog and get attached. This place doesnt only tear apart your wallet, but it tears apart your family and the dogs that live there, being constantly introduced to amazing owners and being ripped from their arms minutes later because of the astronomical price. Never go here, it's nothing but a con. Nobody's gonna pay 11,000 for a dog that hasn't been trained, has very unreliable and rickety medical records and "health insurance." They never ask for any information about your home life or how you'll treat the dog they only care about profit. These people are untrained and disgusting. Don't go here, go to a real breeder and support someone who really cares instead of these sickos.

If I could give 0 I would. This is a puppy mill. There site is full of lies. They don’t care where the puppies go as long as you can pay the astronomical price. They asked me nothing about myself, living situation, job just nothing! I looked at a teddy bear puppy. They told me it’s $10,000. That is 5 times more then most breeders. I looked at multiple breeders all over the country. These dogs are from $1,200 to $4000. This is so sad and a horrible place. If anyone knows where we report puppy mills please let me know because my heart breaks for these dogs. No breeder in their right mind would sell to this company.

There are many more. This place needs to be shut down. When I took my puppy to the vet. The vet the professional said our dog was underweight and was not fed the amount she should have.  Also in-person the lady never told us our puppy had a pre surgery hernia. The owner does not care about the health of these puppies. Also the people that work there are not experts. 99% of their 5 star reviews are fake. This place needs to be shut down. These puppies need to be saved. This is a terrible puppy mill. Just google them Mynextpuppy.com and read the REAL reviews of the place. WE THE PEOPLE ANIMALS LOVERS LETS SHUT THIS PLACE DOWN. LET'S MAKE A CHANGE!
