Big dogs n' money

Saint Bernards are Big dogs.
Saint Bernards cost a lot to raise.

The bigger the dog, the more it will cost you over the course of its life.
Really.
Some people don't realize this.
Sure there are some costs that a tiny yorkie
or shih tzu or rat terrier will have that a huge big dog won't. Clothes. Hair cuts (though many get their big dogs shaved or at least washed. Carriers.
But a big dog is going to cost you money.
They will cost you more in everything - from collars to bowls to time spent exercising.

So when you bring your brand new Saint Bernard puppy into the store and tell me
"I need the cheapest dog food you have because he's going to be big and I can't afford to feed him"
The look I just gave you means 'did you not KNOW that before you got him????"
It also means "I wonder who will have this dog this time next year because you can't afford to keep him?"
There are lots of dogs out there that need homes. Look at your budget before you fall in love. Dogs are not throw away items. They need care. From food to grooming to training to vet bills - it all costs money and your craving for a puppy does not negate the fact that they, like kids, do not live only on love.
And, by the way, the cheap food isn't always the cheapest. Do your research.
