Im in dire need of rehoming my puppy. Please help!!

I rescued a puppy, his name is Scooby, along with his brother and mom off triple x rd and took them in to care for them during their stay here Ive realized im allergic to the puppies. One of them is mine, but I cannot handle him without breaking out in hives, burning in my lungs, wheezing, and/or coughing. I believe its the specific breed he is that causes me to react as badly as I do. Because since I am a dog groomer I havent had any reactions to other dogs except for pitbulls. Im not sure what to do but he does have a courtesy post on forgotten rescues im just at a loss of what to do at this point because it breaks my heart to rehome him because he is a great dog and has such a great personality but I just cant keep him with how badly my health has gotten and any advice or pointers would be great! I am getting him neutered very shortly here. Scooby was found on Triple X Rd on the side of the road covered in fleas, ticks and worms with his mom and brother. He is now just turning 7 months and is very high energy and think and active family would be perfect for him and also someone who has a fenced in yard. He is up to date with his vaccines, getting neutered soon, and is also microchipped! He still needs to be neutered but has an amazing and goofy personality that anyone can love, which was a reason I fell for him, but due to my allergies and with me breaking out in hives this makes it really difficult for me to make this decision. He gets super excited around the cats and likes to chase, but is learning that when he sits down and lets them come to him he can interact with them. With new dogs sometimes he can be a bit vocal, but otherwise I have had no issues with him and he LOVES..people and often tries to greet them. He does get excited with children but on leash, des
