We have an 8 week old puggle puppy and live in a condo building. We crate her next to our bed at night and we leave her crated for 3 hours in a row in the morning and then another 3 hours in the afternoon.
Having to leave her really tears us appart because she cries and cries while we leave and pretty much any time she is out of our sight. Even at night she only goes a few hours without starting to cry. We then take her out and she goes to the bathroom but continues to cry afterwards. Pretty much whenever we don't have our eyes on her she cries...
Right after work we walk her for a good hour and play with her in the condo and in the park every night until she is just exhausted. But like all puppies, it doesn't take long for her to get the energy back up!
Sounds like you are doing all the right things! Play! Play! Play!
When you do get her out of the crate try not to make a big deal out of it because then it will seem worse when crated. Let puppy out of crate (and probably right outside for potty) then once inside give a big happy greeting.
Maybe give puppy some fun toys exclusively for inside the crate so they are more special to play with. Make sure the toys are SAFE (like a kong with peanut butter) so the puppy doesn't get hurt while unsupervised.
Do NOT use the crate as a time out or puppy will associate it as a bad place. Make it fun place to go to and puppy will probably not whine as much but time will help with that also!
I also have a puppy who's exactly 13 weeks old today. :) An 8 week old pup is very much like a newborn. Scent is everything to them. I would leave an old t-shirt of yours with her in the crate. Make sure you've worn it so as your scent is on it. She will feel less alone with it! :)
We have a Puggle Puppy who is about 3 months and sometimes he gets completely crazy and just wants to bite everything and sprint around. We take him outside regularly and don't know why he is so nippy. Most times he listens fairly well and will even sit on comand even though we haven't really trained him to do that. Why is he biting and nipping so much and what can we do to help him not do that? Thanks in advance for tips!
Making sure they're are blankets in the crate and leaving a worn T-Shirt is a good idea, just make sure there's no perfume smell on it, such chemicals can be harmful.
I have read somewhere that you shouldn't make a big fuss when you leave or return or else you could create a separation anxiety in a dog. Mine had such trouble. Remaining calm when leaving and returning could help. Try to avoid a dramatic fare-well and reunion.
