My dog is 5, high energy. She often has a shaky back leg when we're out walking - I've assumed it's just excitement as it tends to be when she I'd very engrossed in something or waiting for a ball to be thrown etc but recently she seems to get shaky legs at random times, and I'm now fretting a bit it's something neurological 😬 She has no stiffness after exercise etc. Any advice or does anyone else have a randomly shaky dog?
