what does a american bull dog look like
American Bulldog The American Bulldog is a stocky, well built, strong-looking dog, with a large head and a muscular build. Its coat is short and generally smooth. The breed is a light to moderate shedder. Colors, while historically predominantly white with patches of red, black, or brindle, have grown in recent years to include many color patterns including black, red, brown, fawn, and all shades of brindle. The color conformation is quite varied, but solid black or any degree of merle is considered a cosmetic fault, and a blue color is a disqualification by the NKC Breed Standard.[1] Black pigmentation on the nose and eye rims is traditionally preferred, with only some pink allowed. Eye color is usually brown, but heterochromia also occurs, although this is also considered a cosmetic fault. American Bulldogs are known to drool more than other breeds of dog. The Bully type is generally a larger, heavier dog with a shorter muzzle. Standard types are generally more athletic with longer muzzles and a more square head. Many modern American Bulldogs are a combination of the two types, usually termed "hybrid." In general, American Bulldogs weigh between 27 and 54 kg (60 to 120 lb) and are 52 to 70 cm (20 to 28 in) at the withers, but have been known to greatly exceed these dimensions, especially in the "out of standard," nonworking stock.
Jack Russell Terrier The small white fox-working terriers we know today were first bred by the Reverend John Russell, a parson and hunting enthusiast born in 1795,[1] and they can trace their origin to the now extinct English white terrier.[2] Difficulty in differentiating the dog from the creature it was pursuing brought about the need for a mostly white dog,[3] and so in 1819 during his last year of university at Exeter College, Oxford,[4] he purchased a small white and tan terrier female named Trump from a local milkman in the nearby small hamlet of Elsfield[5] or Marston[6]). Trump epitomised his ideal Fox terrier,[7] which, at the time, was a term used for any terrier which was used to bolt foxes out of their burrows.[2] Her colouring was described as "...white, with just a patch of dark tan over each eye and ear; whilst a similar dot, not larger than a penny piece, marks the root of the tail."[8] Davies, a friend of Russell's, wrote: "Trump was such an animal as Russell had only seen in his dreams".[4] She was the basis for a breeding program to develop a terrier with high stamina for the hunt as well as the courage and formation to chase out foxes that had gone to ground.[9] By the 1850s, these dogs were recognised as a distinct breed.[10]
