I purchased a puppy from chihuahuateacup.net, took him to the vet and the vet told me he was younger than I was told and ultimately grew larger than was listed on the site, so in that sense absolutely there was deception. He was however, perfectly healthy and has a great temperment and personality. It's sad that the there is some shenanigans going on with the ages and weights of these dogs. I also worry about how many litters are being bred, since there are always new ones year round.
Do your homework when selecting a breeder and don't simply make a purchase based on pictures.
I couldn't figure out how to edit my post to add this, but chihuawow.com is absolutely run by the same people that owned chihuahuateacup.net. If they aren't affiliated then chihuawow.com stole testimonials from chihuahuateacup.net. You can't have it both ways, either chihuateacup.net stole your pictures or you stole their testimonials. It would have been better just to not respond than to prove how dishonest you are. Sometimes it's better just to shut up and have everyone think you're a liar than to open your mouth and prove it, to paraphrase the old saying.
