My puppy is shaking & not her happy self. Usually jumps out of bed, runs in the house & carries on like a pork chop. This morning had to pick her up, shaking & not real responsive. Curling up on lounge & that was it. Put her outside to do business & just curled up on bean bag. Just brought her inside again, still shaking & just wants to lay & curl up. My puppy is 20mths old, playful, over energetic, runs everywhere, no stopping her. This is not my little girl. Can you suggest if there is anything to worry about. Need help as we love this little girl & don't want anything to happen to her. Jack Russell.
Cheers.
