Temporary foster for a dog due to a baby with a dog dander allergy

Hello,
I have a 5 year old chocolate lab that I am hoping to find a temporary shelter for. I have a 17 month old son who is allergic to dog dander along with a host of other things. I have for the most part been able to eliminate the other things that he is allergic to such as food and detergents, but I have not had the opportunity to find somewhere for my dog to go. I am not requesting to give him completely up at this time as I would just like to find somewhere to house him temporarily to see if he is what’s causing my son to continually be broken out and having allergic reactions and make my decision from there. It has been difficult finding a family member or friend to take him as I understand it is a huge responsibility for someone to take a house dog. If you could point me in the right direction that would be great. I can be contacted at 313 980-1254 or dorseytracee2001@yahoo.com
