@gym_class_hero For short : To tire out your dog you need to let them snoff on walks, play with them and mentaly stimulate them.
Teaching random tricks is a very good way to tire out a puppy and havong fun at the same time.
Chew toy and frozen kong can help with the destruction at home.
7 month is a difficult age. Tge pup needs to learn to calm down and good structure at home. Biting stuff is not okay, playing rough with human is not okay.
Now the longer version if you want an exemple based on personal experience:
I have a Husky (10m) in an appartment and she is a very happy puppy.
I do not think apartments are bad for dogs. I think they are actually good because they mean you HAVE to spend time with them which is super cool for them.
I do a 40m walk in the morning. Our walk is 10m sniffing, 20m playing (running after a ball, a flirt pole are playing with a dog), 10m training with her breakfeast. We then go home. If I haven't given her her whole breakfeast during training, I give her what's left at that moment.
I go to work, she stays alone for 9 or 10 hours. She has 2 bowls of water and safe chew toys, I let her freeroam in the living room where there is nothing for her to destroy, but I lock the other rooms. She has access to her crate where she enjoys sleeping.
10 hours later, I come back from work, and take her for a 1h20 walk. We vary the night walk along the week. Sometimes we will do more training and exposure, sometimes it's just playtime with dogs, sometimes it will be going to new streets to sniff, going to a café, running beside the bike and we also start training for bike joering.
After the walk I will spend some time brushing her while we watch a movie, or stuff like that.
Sometimes she needs more than this, sometimes less.
But I wont lie. I do sacrifice my social life at work for her. Sometimes that makes me a bit sad, sometimes I will stay for an afterwork anyway(I take her out at noon in that case) and she is NEVER happy about this hahaha, but I have the right to live sometimes too.
And when she was 7m she destroyed 3 backpacks of mine, lots of socks, lots of sponges(she goes crazy over sponges), my kitchen door has claw marks on it and she ate her house leash, all of this in a 2 weeks span, the time for me to realize we had entered teenage time and I needed to adjust the walks, training and structure at home.
Anyway, hope that gave you some kind of perspective. Wish you the best!
