Dogs are not birds.
In general dogs are not allergic to birds. If you suspect that your dog might be allergic to birds then you should consult a vet.
well depends if you like birds or dogs but is it was legendary birds it would be more rare
Assuming the dogs have four feet and birds two, you need 15 dogs (60 feet) and 1 bird (2 feet) giving a total of 16 birds and dogs and 62 feet. None. Dogs have paws, not feet. Also, birds have claws, not feet.
Yes, if you go back far enough.
no
i think its because birds are in the dogs space and they are the king of the backyard and plus the birds are moving targets. it also might have something to do with entertaining them selves.
they kill birds
no
Based on raw stats the birds would be better than the dogs.
Humans, dogs, cats, birds, I could go on for a while.
