Got a dog?… Learn his language
In certain circumstances we all can have lower tolerance to discomfort, remember how you feel when you have a headache or you’ve had a stressful day.
Know your dog, know how he is today… not how he generally “is”.
When allowing a child and dog to interact don’t expect your dog to tolerate anything a cat wouldn’t and don’t allow a child to cross the line, they both depend on you as the responsible adult.
Your dog has a very broad repertoire of body and facial gestures, learning how your dog communicates will ensure an all round better relationship and deeper understanding between you both.
