I have a jrt cross, who looked similar when he was a puppy.
The benefits are;
Really easy to train as he's so clever, he knows loads of tricks, picked up toilet training really quickly etc
Loves to play, would play all day
Loves people and kids, once he's decided you're a friend he will be very loyal and affectionate.
We do agility and hoopers with him and he's very good at both.
Very good out and about, can take him anywhere.
Very good in the house, never has issues with chewing or being destructive.
Negatives.
Not great with other dogs, he's stand off ish with most dogs and can be reactive to some.
Needs two decent length walks a day otherwise he's bouncing off the walls a bit.
Can be a bit barky in the garden although we manage this by bringing him straight in.
