New dog allergies

I’ve grown up around dogs my entire life always had pit/bully breed type of dogs.
About a year ago I got a new dog as I moved into my own place. My new dog makes me VERY itchy on my arms if I touch anything close to his paws if he rubs up against me or scratches me it itches. My forearms have broken out in hive looking bumps a few times from either us rough housing or just him trying to cuddle. It’s really only my forearms that have that bad of a reaction.
I love my dog and want to be able to cuddle with him, play with him/ give me the physical affection he loves without me itching to death.

Has anyone else experienced anything like this?
