A few questions about Bear pooping/peeing

1. I would expect, with a nine week old pup, to get up at least twice in the middle of the night (one of the many reasons I'll be sticking to adults), he should not be expected to hold it all night, he's an infant. Also how large is the crate? He should be able to stand, turn and lay down but no more or he'll choose one side as potty and one as bed. Make sure you are cleaning the crate with an enzymatic cleaner like nature's miracle (or anything with enzymes in the ingredients) so there are zero traces of urine remaining.

2. Dogs pee more than they poop so they get more practice with that, they are praised more often for peeing since they do it more so that comes faster to them. just continue taking him out every 1-2 hours and remember to praise as soon as he finishes. Do not let him out of your sight in the house, leash him to you so he cannot run off and hide to poop, every time he poops inside it's one less chance you get to praise and one more time the dog learns the house can be pottied in. How often does he normally poop and do you have him on a feeding schedule?

3. Well my dog just taught himself to whine to go out, he'd come and sit near us and whine while he stared at us. But you can train your dog to do whatever you want. the bell is recommended because you are not always gonna see the dog sitting at the door, with a bell you can hear it across the house. Do you know how to train this or would you like help?

Remember he is still a baby and if things had worked out normally, you would probably not have him yet (small dogs should stay with mom and litter mates until 10-12 weeks). a few things do worry me about him being taken so early, he has not learned some valuable lessons from mom and litter mates such as how to control his jaws and he has had NO competition from his litter mates, he may have trouble dealing with frustration as he has always gotten his way with having things like toys, food, attention etc. So you may want to do some of that stuff. Leash him, toss a treat across the floor and see how long it takes him to stop fighting to get it. Now fighting long is not necessarily bad, just means he's determined, you want to watch for him starting to escalate into hysteria, barking while struggling at the end of the leash, slipping and falling while basically throwing a temper tantrum. he would not look like he's having fun, he would look frustrated, restless, nervous even. Or he may be perfectly fine. It's something to try, even if he's fine it's good practice for him to be patient. When he settles give a release word an let him go to his treat.

As for agility, right now I would just start with some basic stuff like sit and down and focus (look right at your face). You can work on building his confidence as well, many dogs are nervous at first abut walking on teeter totters or jumping bars etc. So get him used to different things like that. Right now his balance might not be good enough to walk on planks but just getting him to walk over a bar on the ground and on different materials and textures (including things that are not all that sturdy, as a teeter totter would not be) will get him used to that, always keep is short and fun. If you go for a walk in the woods and you see a fallen log or something encourage him to jump on it. Any opportunities, jump up on a bench in the park or go down a short little kids slide at the playground (make sure you have control of him so he does not stumble) etc. Anything that socializes him with "new" is good, remember praise at the end. Drop something on the ground and praise him for not getting scared. All these things build confidence and socialize him.
