Besides the obvious strain it puts on the mommy dog for dumb reasons, the puppies are almost always of poor quality. Maybe not right away, it might not happen for years to come, but it does happen. Think of the future owners. When you bring a dog into your house you brign the vet bills too. 11 years ago my mom bought me a sheltie. She has been a wonderful companion since the day she came home with us. She was bought from a puppymill. Not one of the discusting ones you hear about, but it still was a mill. They had over 10 litters available at the time. That is too many puppies! Anyways, we love our Shelby to bits. I am not into showing so I do not care about papers and show quality. But physically she isn't doing so well anymore. She has thyroid problems, a terrible coat, she has to be on two different types of medications daily, and we have to put artificial tears in her eyes every four hours for the rest of her life because her tear glands are destroyed. Her eyes are all fogged over, and we think she's a little hard at hearing. Still she is a happy old girl who's full of spirit. Some of these things might just be from old age, but there is a possibility they are from bad breeding aswell. Everyday I watch my dog get a little closer to dying. 11 isn't even really that old for a dog. She looks like she's 162. Our vet said she isn't suffering and that there is no need to put her down as long as we keep up with her special needs. Why would anyone want to breed their dog to produce one that will eventually turn out like mine? Sure, good breeder'ss dogs may turn out like that too, but test your pooches before breeding. It might spare us a couple that will turn out like my beloved Shelby. That's my story about my lovely old sheltie who's sleeping on her bed (yes, she actually has an entire bed) in the middle of the living room. If you really want to experiance birth foster a pregnant dog, please. The world doesn't need anymore heartbreak. ... Well, that's my first post. I am Paige. I own one 11 yearold shetlie, and two four and a half month old boarder collie puppies (I also own other animals, but it's really not important). One of the pups we were babysitting and the owner just never came and picked him up. I'm not sure how much I'll be posting, but you'll see me around I guess. I have been reading the breeding threads for awhile before joining and I think the uneducated people really do not understand why they should not be breeding their common family pets. You guys all talk about the health of the puppies, but what happens when they become full grown dogs? Well, your dog might turn out like my little girl. Not saying she is a burden and I am not against breeding (though I do think adoption is a better choice if you are in a position where you can adopt). It preserves the breeds we love so much, but only if you have the knowledge to back up your actions. I am starting to preach, so I will shush now.
