Human-directed aggression in dogs is a serious problem, both for humans and for dogs. It deserves serious research. We need real data. Not the perpetuation of assumptions and stereotypes.

[Hecht Lab @LabHecht]

Some media are reporting that our recent study (https://t.co/Ec247zlPkq) shows that pit bulls are especially likely to become aggressive if they are exposed to early life stress. Simply not true.

[Hecht Lab @LabHecht]

So why is the media reporting that pit bulls are especially likely to become aggressive if they experience trauma? One possibility: hallucinations from LLMs that generate initial drafts of the news articles. AI reflects the biases of our culture as a whole.

However, just because a dog has a certain background, or comes from a certain breed, doesn't mean they are destined to behave a certain way. Many factors go making each dog who they are, and breed and life history are just two pieces of the puzzle.

[Hecht Lab @LabHecht]

If you have a rescue dog, you might have the sense that stressful experiences can impact dogs' behavior later in life. Well, we just did the largest study ever on this topic. Open access! https://t.co/Ec247zlPkq

Why is this important? If we can identify the genes and pathways underlying this risk and resilience, we might be able to develop targeted interventions. We are already analyzing the dogs' DNA samples and MRI scans!

Hey @colossal. Wanna scan your dire wolves' brains? My lab at Harvard University does non-invasive MRI scans in dogs, foxes, and more!

[Hecht Lab @LabHecht]

Using non-invasive MRI, we found a pathway in dog brains that predicts receptive vocabulary size. It’s left-lateralized & connects regions that produce and perceive vocal communication. A convergently evolved arcuate fasciculis? Read at @CurrentBiology: https://t.co/nTrX3aQGPV

I emailed Dr. Trut as a no-name grad student asking if I could do MRI research with her foxes. She didn’t write me off & 15 years later I have a lab at Harvard continuing to study the amazing animals she helped create. She made an impact in science & my life. Thank you, Dr. Trut.

Come see @Sophie_A_Barton’s talk if you’re at #sfn2024! Nature and nurture in the brain organization of domestic dogs!

[Sophie A. Barton @Sophie_A_Barton]

I’m giving a nano talk at #sfn2024 #SfN24 tomorrow! It’s at 1 pm in room N227 if anyone wants to come learn about working dogs and their brains
