the thing is, I think if you are on this site you will already KNOW what we would think of a website advertising "designer breed" puppies!
This is obviously a puppy mill.
puppy mills are responsible for some of the worst cases of animal abuse and neglect in our countyr.
puppy mill puppies OFTEN have both major and minor health issues, (and if you are one of the 1/2 of 1 % who got one and is happy with it, then good for you, but for every one of you there are a thousand with liver shunt, encephallitis, behavior and neuralogic issues as well as a host of other problems)
no one should ever go hunting for a puppy solely on the internet. You need to find a breeder, talk to their references, see their "operations", meet the parents and get a feel for how they run their breeding program.
and it doesn't hurt if they are on YT!
but we are just telling you what I think you already know.
