Mixes are not bad, but sometimes people who breed "designer dogs" such as doodles and poos and whatever are not very ethical. It's unfortunately the case the majority of the time with designer dog breeders. They're in it for the money and little else. Betterment of the breed and healthy dog is typically not at the forefront of their mind. That doesn't mean there are no mixed breed breeders who are ethical, but you must carefully do your research to ensure you are not supporting a breeder who slaps a male and female together and hopes for the best.You asked why we want this in particular. We love the tricolor. And love the Bernese mountain dog but their life span is extremely short. And they are too big for our space. And poodle mix is great for being hypoallergenic and less shedding .. so it seemed like a great mix. If mixes of dogs are bad as you are suggesting.. I’m just not understanding why mixes of dogs at a shelter our different? I’m trying to understand. But yes.. I would love to find a local ethical breeder of what we like.
