Pet Blood Bank Uk

I recently heard of plans to establish a blood bank for pets in the UK. It made me think:

a) Dogs and cats have different blood groups?
b) Are they classified as the blood of man namely A + Abnegation etc.?
c) Can a cat receiving a blood transfusion from a dog?
d) If the blood can be used across species, and humans may receive blood from dogs, etc.? Can dogs get the blood of man?
e) If blood can not be used in all species, how does this affect different breeds of dog? Can a Chihuahua have the blood of a Great Dane? Where does the end of the line? Could wolf blood be used? How about blood hyena?

Pending some interesting answers!

It is not possible to use the blood through the species because each species has a different number of chromosomes. For example, a dog and a cat is 78 to 38. This means that the chances of a successful transfusion is better although still almost impossible between a species that is close to the number of chromosomes, for example, a man (46 chromosomes) and an orang-utan (48 chromosomes) a man and a cat. The different species are the equivalent of different blood groups, see http://www.messybeast.com/bloodgroups.htm

no, they have no blood different "types" like humans. If a dog needs a blood transfer, they can use any other dog regardless of breed, but a large dog is probably preferable because they do more. how ever they can not use blood from a dog or cat to an animal for a human being
