See, if a person is a dog-hater, that explains a lot of things and we know what to expect from him. But what about people who profess a love for their dogs, only till it is convenient, they are being entertained, or their house does not need remodeling (example 1, example 2).
Relationships are a two-way street, and our dogs may have needs which inconvenience us, cost us money, our time. And this is where you have to ask yourself - you love your dog, or yourself?
Frankly, if someone can unload their dog like this, then for me, they do not have a true relation with anyone.
