1.) Crate him all the time if the Terrier is present and is in heat (Yes. For all 3 weeks). Only comes out of the crate to go potty and for walks. That is how male dogs are handled when female is in heat. The Terrier should likewise be crated the same way when in heat if the male dog is there. NONE of this is "fun" and the male will whine. Constantly. Breeders deal with this.
2.) Keep him away from the terrier whether she is in heat or not due to her presence being a trigger for him to act like a male and mark territory.
3.) Use a crate. In your house. Terrier or no terrier. Go through the entire potty training again with the male. Crated when you are not there. Let him out. Praise and food when he pees outside. NO punishment when he pees inside.. simply watch him all the time and if he goes to lift his leg, interrupt and get him outside.
He is doing this in response to being around a dog in heat. Once the behavior has been established, neutering usually does not help and neutered male dogs may pick the behavior up when exposed to a female in heat. Punishment is not a good route to take with potty training (trust me, I DO use e collars and prong collars and I do use positive punishment.. and that use is VERY limited as positive punishment can have fall out if not done right).
Never use positive punishment with potty training. All that does is teach the dog not to potty in that spot or in front of you.
Good luck.
