In many ways, it's much nicer living with a dog than a human - they're happy when you get home, they're more fun to be around and they chat less s***.
On the other hand, they are more likely to do a s*** somewhere you'd rather they didn't. Ordinarily, this is because they're not toilet trained or haven't been allowed out for a long time.
But one woman in the US is insistent that when her pug does a poo in the house, he does it with intent.
Holly Munoz, from Kentucky, says her seven-year-old dog Frank is totally house-trained, however, when he feels wronged in some way, he exacts his revenge by taking dumps on her possessions.
The assistant charity director first fell victim to his foul practice when she returned from holiday last year to find a turd waiting for her on her pillow.
The 40-year-old had an inkling that Frank did it to avenge her after she left him with a dog-sitter, and since then, he has brownmailed her 15 times - mudding inside her shoes, make-up bags and on a box of crackers.
The mum-of-two said: "You name it, Frank's pooed on it. He has incredible aim. He definitely does it on purpose, he wants to make sure we know he's angry.
"One time, I came back from a trip and he had pooed on my crackers and in my makeup bag. He's an angry pooer. If we go on vacation then he will poo on something.
"My son, Oliver, is his favourite person, they sleep together and they're attached at the hip - so when he went to a sleepover Frank was annoyed and he pooed in my shoe.
"I'll probably spend the next seven years finding and cleaning up his angry poos."
But despite all of the dog's dirty protests, Ms Munoz still loves him.
She said: "I picked him out of a whole litter and made him a part of our family, and you can't un-family someone just because they poo in your shoe.
"We have three other dogs but we know it's him every time. He doesn't even have a guilt face, there's no shame at all.
"We foster dogs and we think he'll do it if he feels slighted or because he wants more attention. But I still love him. He is the most loving dog. He loves the kids and every time they aren't here he's beside himself."
