A Miami man is facing five years in prison and up to $10,000 fine for animal cruelty after allegedly beating a four-month old Beagle so severely that the puppy was dead just one day after he adopted her 

Matthew Milewski, a high-frequency trader, adopted the puppy, Molly, from a Arkansas breeder Outback Beagles, who call their dogs 'friendly and loveable, with tail perpetually wagging!'

But just one day after getting his new best friend, Milewski had allegedly whipped Molly with a leash, slammed her against hard surfaces, and drug her across parking lots until she was bleeding.

He put an electric-shock collar and leash on the new puppy the next day and began to walk her through the building's parking lot.

Carlos Gregorio, a valet parker in the building, told police he he heard a 'loud scream from a dog' just as he was bringing a car from the garage. 

At first he thought he'd hit an animal and jumped out of the vehicle.

Then he saw Milewski, 'striking his dog with leash.'

'Dogs don't become extremely obedient with rainbows and sugarplums,' he said, admitting  that it may have appeared 'abusive' to onlookers who didn't know what he was doing, and that he'd been trying to train Molly in a 'very aggressive' way. 

Outback Beagles disagrees, noting on their website under training information that for Molly's particular breed: 'Praise is the key, as they thrive on positive attention.'

Milewski told investigators he wanted to clean Molly after he noticed one of her paws was bleeding.

'When I went to put the dog underneath the shower head, it didn't like that at all and it bit me,' he said. 'I was very shocked. I don't like blood. When the dog bit me, a lot of blood came out and I overreacted to the dog doing this.'

Exactly how he reacted is unclear.
