Congrats!
Unless your husband has an allergy to the saliva, he probably has allergies similar to mine. I am allergic to short haired, shedding dogs. I get itchy, my arms turn red (cause of course, i pet them), my eyes itch and my asthma acts up. I'm usually OK after an allergy pill and a shower.
I am NOT allergic to my Yorkies. I bathe them once a week (at least) in Buddy Wash. I keep them clipped short to that it's easy to blow-dry them after a bath and it's easier to keep them clean.
Be careful with all of those "allergen reducing" products. I'm allergic to the chemicals in them and they just cover up the problem. I use Buddy Wash which is all natural, and Simple Solution for accidents and wash their faces/feet with a warm washcloth and a tiny but of Buddy Wash. Laundry gets washed often (dog beds, blankets, etc.) in my regular organic laundry detergent.
When I got Sammy, I thought I was allergic to her but actually the person I got her from had just used a scented grooming spray. Once I washed it out, she could sleep on my pillow, no itching or sneezing
Good luck!!!
