Often people make the mistake of not training their animals.
I have seen people who train dogs in agility trials who dont train their dogs that they are not the king of the house.
Its very annoying to see a dog that does not know its place.
Dogs will do all kinds of aweful behavior around humans including family members if they are allowed to believe they are higher in the pack order than the human.
Dogs can be great members of a family if they are taught that they are at the bottom of the pecking order
We have five dogs and they know their place. I am the Alpha male and Mrs SLB the Alpha female.
