I believe it would not help you to test your partner's reaction on one dog, he should test his reaction on exactly the dog you would wish to have. I do have numerous allergies, very bad reactions on cats, but have had dogs all my life. I sometimes realized some allergic reaction on other dogs, but never had any problems with my cocker spaniels. My nieces in Gloucester have three cats. It is always very painful for me for the first 3-4 days when I go to see them, but after that short while my immune system seems to adjust itself to this different situation.
