If by kind you are referring to the Biblical idea that organisms are related then yes they are. All canines (not just common dog breeds) are of the same kind. A wolf could breed with a beagle or chihuahua and have (odd, but probably healthy) puppies. According to modern classification, common Dog Breeds are just a subspecies of wolves and such.
Dogs can pretty much get the same illnesses as humans can.
Yes they can do the same thing as people. They have the same kind of brian as peole. Dogs can do anything people can do can do anything that humons can do.
Guinea Pigs don't have the same saliva as dogs.
Only Pure Bread dogs can be entered in competition. Ones that have parents of the same kind of dog and that are not mixes or in other (harsher) words "muts"
The same things that make a human sneeze....ie black pepper.
Most dogs have a covering of hair and skin.
What kind of a question is this. These dogs are owned in much the same ways that trained horses are. No they do not kill the dogs after the races. Or they may "retire" them meaning, they find homes who would like to adopt them.
Smaller and fanicer dogs
puppys because they are dogs
The Pharaoh Hound
German Shepards. Dogs do not have ideologies though.
I'm pretty confident that Yorkie dogs are the same as teacup dogs
