It could be one of many breeds. If the cat came without papers it is probably a moggy - A Domestic Shorthair. These cats are of mixed lineage and so can come in many shapes, sizes and colours. Some even may look like a pedigree cat but without proof of its lineage they are still called moggies.
sounds like a mutt to me
No, they usually do not. White spots on the chest, tail, or paws points towards a mixed breed. You may want to check with your breeder or vet if the dog was supposed to be pure-bred.
That could be many breeds......be more specific. Is it small, big, tall, short??
Usually one of two breeds. Either a Pitbull or a Boxer. Brindle coloring, one or more white paws as well white markings on chest and or nose are indicative of both breeds. The boxer will have a very short nose/snout.
A black-and-white cat. They can also be called tuxedos if they have the right patterns: white on their chest, tummy, and paws and there can be some on their head, face and neck then the rest of them is black.
western white terior
maybe the husky
The Birman is a breed of cat that is distinguished by blue eyes, white paws, and a silky coat.
she is a light brown tabby she-cat with amber eyes, a white chest, and white paws.
There is no way to tell just by the colors what breed that cat might be. It is most likely mixed breed, though.
Tuxedo? but that is when the cat is black, has a white chest, and white paws, sometimes some white on the face, and sometimes a white under belly, hope this is what your were looking for. :]
No cat breed as I know if is restricted to only that colour pattern. It can occur in many breeds, mot notably the domestic. A domestic is a no breed cat but different countries domestics can look different. An American Domestic shorthair can be more leaner and slender than the British Domestic shorthair. I owned a black cat with a white face (how you described) but she also had white paws and a white chest. They look similar to cats in tuxedo's.
