I started looking into this about 5 months ago. I did a web search for "blood, dogs" and came to a web site that was the project of a 'dog donor farm' (I'm sorry, it's Friday afternoon and I have to get home, I don't have time to look up the reference).
That site indicated that there are 7 dog blood types, and there is one universal donor. I am unable to provide or find any information as to whether the dog blood types are the same etilogy as human.
The downside is that very little data is available for any individual dog's bloodtype. It is rarely recorded, and animal owners don't want to pay the fee (~$35-40) to have their dogs typed when there is no obvious benefit.
Any grant put together would have to sponsor:
a) typing the dogs
b) testing the foods on the blood types
c) mapping diseases to blood types.
This is way beyond my ability, but it sounds like Jean is just the person to do this.
Anybody interested in historical factoids can try searching the site to find my original post. I'd be curious to know what I said.
