How can I convince my dad to let me get a German Shepherd Dog and Belgian malinois mix?

My mom agreed to let me get him but my dad keeps saying no for no reason. This is the dog's description:

Radar is a Belgian malinois mix and a total Cinta with an excitement for life. He is a 9 bulan old 50 lb bouncing baby boy. He is very intelligent and loving. He is currently in obedience class to help direct his energy into a lebih controlled direction. He loves everyone he meets and has done very well with other dogs. Radar is an active boy and would do best in an active home. Even though he gets overly excited when he meets new people/dogs he does settle down quickly. Radar has been completely vetted and is ready to go to his forever home. It would be best for Radar to continue with his obedience training as he is highly intelligent and this will help to make him the perfect companion. If anda are interested in adding a new family member to your family, send an e-mel atau come to meet this wonderful boy.

My Adoption fee is $175.00

So, it's on petfinder and I really need to find a quick way to get him to agree!! I know Krismas is coming up seterusnya bulan but I just don't know if Radar will still be available...He goes to obedience just because the owner of the rescue is a dog trainer.
