I have worked in dog grooming and doggie daycare/ boarding facilities since year 2011. For the last eight years I’ve learned hands on from certified trainers, groomers and breeders. How to handle timid dogs, aggressive dogs, mis-behaved dogs. All dogs simply want to please their humans and be loved. I think that some people don’t understand that they can’t express to us humans clearly what they want and need... for instance a dog inside a fenced yard is barking at you walking your dog(s) along the sidewalk.. Some may think that dog needs a bark collar or that dog is aggressive. I think that dog wants to play and make friends and the only way he/she could possibly do that from inside a fenced yard is to get your attention, usually the best way to do that, I would think, would be to bark and wag. I think I know dogs in a way many people don’t. <3
