Dogs in the Muggle world
In the Muggle world, dogs also were kept as companions, being very faithful and, with proper training, could guard valuable objects or people or act as service, rescue and police dogs. The Dursleys next door neighbour kept a dog, which Dudley once drove over with a working tank. Harry Potters Aunt Marge bred bulldogs and in 1993 when she visited the Dursley house, she brought one of her favourites who was old and rather ill-tempered, named Ripper. Often in the Muggle world, larger dogs were given fierce names to make them seem more ferocious.
Dogs in the wizarding world
Dogs in the wizarding world also seem to have had much longer lifespans than dogs in the Muggle world. An example of this is Fang, who was born in the mid-1980s and was still alive by 2010, an impressive age for a dog, especially considering that larger dogs like boarhounds are known to have shorter lifespans than smaller breeds.
The Crup was a type of wizard-bred dog that resembled a Jack Russell Terrier, but possessed a forked tail and was loyal only to wizards, and was highly aggressive towards Muggles and Squibs.
Harry Potter considered his treatment while at 4 Privet Drive to be comparable to that of “a dog that had rolled in something smelly”.
After being bit by Norberta, known at the time as “Norbert”, Ron Weasley told Madam Pomfrey that he had been bitten by a dog. She didnt seem to believe him, but was apparently unable to figure out the truth about what had really bitten him.
It is possible that Agnes failed her dog Animagus transfiguration into a dog, as the description of a failed Animagus transfiguration resembled that of Agnes.
