I accidentally found this article from last June from the internet today:
It’s in Finnish but it’s tells about dog breeds that are sick because of selective breeding. In this story they have interviewed Marjatta Snellman, professor of veterinary medicine. She says that animal abusing doesn’t necessary mean just neglecting the animal on “traditional” way, but also by neglecting animals’ rights to healthy life by limiting ability to breath and move.
Dog’s short nose can be very troublesome. They just can’t breath in the normal way. For example Pekingese: “In English National museum you can see the completed Pekingese dog as it was before the current breeding. Its head was a perfectly normal and functional, and the Emperor himself was happy with it.”
Other trouble is too short scull. “The head shape is bred in such way that the brain no longer fits in the dogs’ cerebral cortex. The result is a brain fluid circulation disturbance, which may damage the spinal cord. This leads for example to strong pain.” Cavalier King Charles Spaniel is a lovely dog but this problem darkens its life.
I hope (and believe) that people are coming more aware of these problems so that in future we can have more healthier dogs (and other animals).
