Is Your Dog Newly Aggressive? There Might Be A Pain Connection

German shepherds are just one breed that is prone to hip dysplasia.

Our Chihuahua, Hayley, has been barking at dogs lately on her daily walks.  She’s also begun to scream a bit at certain times when she gets up quickly. I suspect she might have some leg pain, or maybe since she is getting older, arthritis may be a culprit. Either way, a vet visit is necessary.

While her screeching is a no brainer that she is in pain, I hadn’t really considered her aggressive behavior toward other dogs as another sign. However, according to a new study, dogs who are suddenly aggressive just might be in pain.

Researchers at the University of Barcelona studied aggression problems in 12 dogs (giant schnauzer, Irish setter, pit bull, Dalmatian, two German shepherds, Neapolitan mastiff, Shih Tzu, bobtail, Catalan sheepdog, chow-chow and Doberman).

The study showed that “all 11 males and one female were diagnosed as having aggression caused by pain, and eight of the dogs had hip dysplasia.”

The lead researcher of the study, Tomas Camps, said “Dogs that had never been aggressive before the onset of pain began to behave in this way in situations where an attempt is made to control them.”

It’s an even bigger reason to be vigilant when your dog gets older, especially if you have a breed that is prone to hip dysplasia.

Did your dog become aggressive before diagnosed with an illness?
