Hi Aileron is 14 months old. I've never had a dog before so I need a bit of help. Over the last two weeks she seems to just put herself into her cage instead of using her pillow or sofa, also, when at the dog park she only plays fir about 45 minutes. She used to play for much longer. Is that just her puppy leaving?
Yes, they do get older and put away puppyhood eventually. But it could be that she's feeling a bit off, too, so just keep an eye on her and see if any other Behaviour changes happen. If you are worried than best to have a visit with the vet.
