yes, you can choose from any type of breed
Cats and dogs both shed, but the amount can vary depending on the breed. Some cat breeds shed more than some dog breeds, while others shed less. Overall, cats tend to shed less than dogs, but it ultimately depends on the individual animal.
None! Both molt, cats molt more as their fur is denser. However you can get special breeds of both cats and dogs that don't molt, discuss which breeds these are with a vet. x
It depends. If the dog is smaller than the cat, or if the cat is particularly feisty, chances are likely that a cat will scare the dog away. Larger breeds of dog, especially breeds with a high prey drive have been known to kill cats, however.
Here is a list of almost all dog breeds known to man, (see related link).
Both cats and dogs shed, but the amount of shedding can vary depending on the breed and individual animal. Some dog breeds shed more than others, while certain cat breeds are known for shedding less. Overall, it is difficult to determine definitively whether cats or dogs shed more, as it can vary from one pet to another.
Because different breeds are one way or another inbred, with the likelyhood of the genes needed for these diseases much higher than in a dog with two or more different breeds in it's ancestry.
Some breeds are just more talkative than other breeds. Some cats rarely "speak".
