I am a former service dog trainer whose own reactive dog forced me to change everything! I now change dogs and families for the better! Is your dog lunging at strangers? What about barking at them?Are you scared they are going to bite someone or have they? Maybe he tries to eat the mailman or even your family member? How about not being able to leave them alone because they eat your home? Hiding under furniture or constantly urinating in your home?What about dragging you down the street? All of these are fixable, by changing your dogs mind about the situation.
