There are loads of breeds of Dogs, like Dalmation, German Shepherd, Husky, Labrador and Golden Retriever. Each has a different personality and some dogs may be good at some things, while others are not, like German Shephers are good Guard dogs, Husky's are good sled dogs and Labradors are good guide dogs.
Some dogs need different things, like certain breeds have a long coat of hair, while others have short hair, the long hair breeds need lots of grooming, the short hair breeds don't.
My fave breeds are Husky, Dalmation, German Shepherd and Labrador!
There are about 800 breeds of dog, some like the Cavilear King Charles Spaniel are bred for their colour, they are also used as pets, the German Shepherd is also bred for it's colour and it's guard dog skill.
There are estimated to be 400,000,000 dogs in the world.(WOW)
Some dogs are cross bred.....that means their parents were two different breeds.....thay may have the skills off both parents.
A dog that is a cross is called a mutt.
