Dogo Argentino

No. The Dogo is a larger, taller hunting breed from Argentina, typically 35 to 45 kg with a long, powerful head and an all-white coat. Bull Terrier is one of several breeds in its background, which explains a passing resemblance, but its size, purpose and history differ. The founders bred it to hunt big game in packs and deliberately selected away from the quarrelsome traits of their foundation stock.

The founders chose white partly so hunters could spot their dogs easily in scrub and tell them apart from the quarry. The standard allows one dark patch on the head as long as it covers less than about 10 percent of the head, while spotting on the body is a fault. White coats bring a higher risk of deafness and sunburn, which is why careful breeders hearing-test every puppy.

Often not, particularly with dogs of the same sex. Many are sociable as puppies and become selective or intolerant between 18 months and three years. Some live happily with one familiar dog of the opposite sex. Plan for a single-dog household or careful management, skip dog parks, and ask a qualified behaviorist for help early if you notice staring, stiffening or lunging.

Yes, with sensible care. The short coat gives limited insulation, so a well-fitted dog coat on freezing, wet days and a warm, draft-free bed matter. Keep your dog moving on winter walks rather than standing around. Most Dogos cope better with cold than with long hours of intense sun, which burns their pink skin.

A completely deaf puppy often sleeps through loud noise, doesn't turn toward voices and startles when touched. Deafness in one ear is harder to spot, because the dog still hears but struggles to work out where sounds come from. The only reliable answer is a BAER test, which measures the brain's response to sound. Ask for results before buying, or ask your vet where one can be done.
