Foxy Behavior: how a Russian fox farm uncovered the basis of canine domestication

by Drew Drabek figures by Nicholas Lue Foxes are not dogs. As a rule, dogs are docile and foxes are feral. You could say it’s in their DNA. But there are exceptions to every rule. A fox raised in captivity might learn to be gentle. A dog who was abused might lash out. Behavior: it’s complicated. There has been great interest in the selective breeding of … Continue reading Foxy Behavior: how a Russian fox farm uncovered the basis of canine domestication

Dogs and humans were buried together in 6,000-year-old graves

A recent study suggests that dogs and humans may have formed close relationships as early as 6,000 years ago — a relationship that involved humans feeding the dogs, but ended with the dogs being sacrificed. Canine remains from this era have been uncovered before, but this study adds 26 more specimens … Continue reading Dogs and humans were buried together in 6,000-year-old graves

Dogs with muscular dystrophy receive CRISPR treatment: What does this mean for humans?

In an exciting step forward, dogs with Duchenne muscular dystrophy (DMD) were treated with the CRISPR genome editor to restore production of the missing protein responsible for the disease. After more studies to prove it is safe and effective long-term, this has the potential to move into clinical trials as a DMD therapy. “[The dogs] showed obvious signs of behavioral improvement – running, jumping – … Continue reading Dogs with muscular dystrophy receive CRISPR treatment: What does this mean for humans?

Dog owners rejoice! Dogs could be smarter than cats

A new study has compared the brains of dogs and cats and found cats wanting. Scientists counted the number of neurons in the cerebral cortex of brains and found that dogs have more than double the number of neurons of a cat. While this doesn’t immediately rule that dogs are the smarter species, it does suggest they have a higher capacity for learning. Continue reading Dog owners rejoice! Dogs could be smarter than cats
