The American Pit Bull in Spain

Although affectionate with humans, American Pit Bull Terriers are strong for their size and can be extremely stubborn if not trained early on in their years.  The bull breeds are often grossly misunderstood. American Pit Bulls  are extremely intelligent and learn commands and tricks with ease, but these characteristics also attract highly unscrupulous people looking for strong competitors for their dog fighting rings. The sorry result is that bull breeds, in particular the APBT  ( American Pit Bull Terrier), have gained a reputation over recent years for being dangerous.

Staffordshire Bull Terrier

Staffordshire Bull Terriers have a low centre of gravity and most striking of all, are the huge muscles and wide jaws. This dog is the picture of power, yet is surprisingly agile and quick on its feet. The Staffy is a dog that needs  close human contact & a chance to play. He is far too much a people dog to be left alone outside all day, and far too much an athlete to be stuck inside all day. Living with a Staffy means sharing time both inside and out. Given proper exercise of body and mind, the Stafford is a well-behaved house dog. Some Staffords are not good around strange dogs, precautions should be made that they not encounter dogs while loose.

The Rottweiler breed have been selected for guarding and protection work, and this must be kept in mind at all times. Well-socialized rottweilers get along nicely with people and other dogs, but males in particular can be a bit aggressive and dominant. Active, intelligent dogs, they are fully confident enough to act on their own, so they need guidance right from the start. Aggression can be a problem, and this dog is fully capable of inflicting severe damage, so rottweilers do need a firm, patient hand and a knowledgeable owner.
