I have no issues with mixed breeds other than they should not be marketed as a "new breed". This is completely false information put forth by people who want to make a quick buck preying on both people and animals. Unfortunately, the human is only out monetarily. The dogs loose homes and love when they don't live up to the expectations promised by disreputable breeders. It sickens me.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3239273361735369973.post-6716166067716009942008-02-14T09:45:00.000-05:002008-02-14T09:45:00.000-05:00As a breeder myself I have to take issue with bein...As a breeder myself I have to take issue with being "less concerned about meeting the breed standard". HELLO....That is what breeders are SUPPOSED to do! If I buy a beagle, I want to know that it is #1 going to look like a beagle, #2 act like a beagle is supposed to and #3 have the temperament of a beagle! People who are out there breeding "for the Benjamins" could care less what they are producing. I breed Newfoundlands and have personal experience in people who come to me with dogs that they say are Newfs but look more like a large lab or a flat coated retriever and yet have all the problems associated with our breed. As an ethical breeder, I do ALL health clearances required plus a couple of extra before I ever breed one of my dogs. I had the #4 dog in the country a couple of years ago but chose NOT to breed that dog because one of the hips was not perfect on x-ray. We ARE trying to "improve the health of our breed" but when you get people who just do it because "My kids need to see the miracle of birth" and take no responsibility of what they've done, then we are left to pick up the pieces of their idiocy.<BR/><BR/>As for mixed breeds (and I have one of those too, so I'm not against them, just do not promote making more) living longer and healthier....that's crap. You see more problems in purebreds because we choose to acknowledge that we HAVE the problem and try to fix it, rather then put our dogs down and get another. These animals are NOT disposable creatures and most people are not willing to put thousands of dollars in their dogs.<BR/><BR/>As for designer dogs, anyone that would pay big dollars for a mutt...a fool and his money are soon parted. You "get what you pay for" but have no idea what you are getting so don't be pissed when you don't it. Thousands of dogs are put down in shelters every year, 25% of them being purebred dogs. Do we really need to make more?

I think this mainly because of the amount of genetic problems showing up in purebreds. <BR/><BR/>Every single scientific study that's been done shows that mixed breeds (or mutts, if you prefer) live longer and healthier lives than purebreds.<BR/><BR/>I think a greater number of people would choose a purebred if the breed clubs were less concerned about meeting the "breed standard", and took a bit more interest in improving the health of their chosen breeds.
