Often called “raised hackles,” dogs do this when they’re nervous, threatened or showing aggression. It’s an adaptation from their wild days of attempting to make themselves look bigger.
Dr. Tammi King, Applied Behavior Technical Leader at Waltham Petcare Science Institute, offered this insight to keep in mind: “What’s important when talking about a dog’s body language is to not take one thing in isolation. You’re at risk of misinterpreting what the dog is trying to say to you. Context is everything.”
So be sure to pay attention to what your dog isn’t saying to keep them healthy and happy. Serving them IAMS dog food every day will certainly help.
