4 year old needing rehomed due to allegies

Max is a loving, cuddle cheeky 4year old who is needing rehomed through no fault of his own as my sons allergies have became too much for him to handle. He is great walking on the lead & doesnt pull, but recall with distractions still needs work so an enclosed dog field is best for him to burn off his energy. He is friendly and playful around other female dogs but I havent had him around male dogs. Its been a difficult decision & breaking our hearts to let him go, but hopefully he gets his new forever home with a family who loves him as much as we do. He will come with almost a month worth of food, a few bones, toys, bedding harness, leads and jacket.
A home check either in person or facetime would be prefered
