I'm back, looking for more advice…
My 16-week-old puppies are adapting to their crates, but still go through freak-out episodes occasionally, where they bite their crates (wire mesh types).
I noticed today when I was looking at their permanent teeth that are coming in along the front that some of their baby teeth seem chipped or broken (the longer canines and ones on the bottom). Not badly, but just a little uneven. Could this be from their crate antics? I am tempted to rub some Bitter Apple on the wires so that they will stop biting the crates. I keep thinking of Oakley's mom writing that he chipped several teeth before he made friends with his crate. However, the Bitter Apple seems like it would be upsetting to them on their crates if it is something that they can smell.
Any input is welcome. I should say that I recorded them today when I left the house for 20 minutes. By 2.5 minutes they were quiet, with only little episodes of whining now and then. They started up again when they heard me opening our front gate. Tomorrow I am going to see what happens when I take one on a walk, leaving the other here (which I end up doing when I have the time for sequential walks, as walking them together is still a nightmare at times).
