Dogs are sensitive to stress too
Researchers videotaped and took saliva swabs dogs during two different types of training - negative reinforcement and positive reinforcement training. While both methods were effective in controlling the dog’s behavior, dogs in the negative reinforcement programs showed more stress-related behaviors during training. Plus, they had higher levels of cortisol too. Showing just how sensitive dogs can be to the way they are engaged with.
How to tell a dog's emotions?
From the above, it’s pretty clear that what we might think our dog is feeling is usually right!
The obvious difference between human emotions and dog emotions is that because dogs don't speak (words anyway.) They use physical cues, so be sure to look out for any droopy ears, jealous snapping, or if your dog seems genuinely sad. Taking them to the vet if you feel they aren’t themselves will never be a trip wasted.
