When someone is trying to have a dog training certification without learning how to interpret some dogs’ barks, it would be like someone trying to get a degree in communication without learning how to interpret people’s discourses.
As you may know by now, having a dog is not as easy as you thought when you were watching dog photos and videos online. It is a lot of work, and it requires some common knowledge as well as some skills to deal with your loyal companion.
A huge part of knowing how to treat dogs is knowing how to speak their language. And believe me, every effort that you will spend trying to understand what your dog is saying would be worth it.
And I am very sure that if dogs had a language just like ours, we would only hear all kinds of sweet things, because I believe that your furry friend is definitely ready to take a bullet for you.
