This Is Your Brain. This Is Your Brain on Pugs.

Written by PETA | August 6, 2010


If you’re a regular PETA Files reader, you probably already know about the physical and psychological problems that plague specially bred (meaning inbred) dogs. Labrador retrievers commonly suffer from hip dysplasia, cataracts, and retinal degeneration. German shepherds are prone not only to hip dysplasia but also to spinal paralysis, epilepsy, and blood disorders. Bulldogs often develop heart problems and hip disease. (Purebred cats are prone to health problems, too, as I discovered after adopting an adult Siamese cat from a local rescue group and finding out that he has asthma—a condition that affects Siamese kitties more than any other type of cat.)

But a new study shows that breeding is messing with more than dogs’ bodies: It’s actually changing their brains. The study’s researchers found that the brains of many dogs with short snouts, such as mastiffs and pugs, have rotated forward by as much as 15 degrees and that the olfactory bulbs of these animals have drifted downward—possibly affecting their ability to smell! Researchers aren’t sure if these changes could also affect behavior, but they may.

This is just one more reason why breeding animals should be nixed—and dogs should be mixed!

    people need to think about the wellbeing of animals before they breed. it should be all about the wellbeing of animals.

    My late Labrador retriever died a painful death because she became covered with fatty tumours which eventually blocked her throat… she was obviously the product of immoral inbreeding no one should ever die like that. my rescue mutt dog ‘on the other hand’ is commonly regarded as ugly merits comparison to foxes coyotes she has dingo ancestry but is much more hardy than my late Lab perhaps even is more happy from the lack of inbred genes.

    i have a dashund that was given to me by a coworker because he has some behavior problems! i think i was at least his 3rd home in his 4 years when i got him! so i’m not ashamed to have a pure breed! he adapts good with my lifestyle and is a really sweet dog just hard headed! before him i had a mix breed rescue that was a lot more easy to deal with and smart as they come! guess what i’m trying to say is at least he has a steady home now and unless something happens to me 1st he will be with me till his last days! already set up a deal with my best friend that if anything does happen to me he will take him in!
