My dog normally doesn’t do much, but she went to doggy daycare 2 days ago and played all day long. She’s been sleeping a lot since then and started walking funny. Should I be worried?

Our 7 month old German Shepard played a lot this morning and took him home. I noticed his hips started wattling and he’s been weak and tired all day. And he won’t play like he usually does, he jumped up twice today after a mid afternoon nap but it seems he’s having trouble getting up on the couch.

Puppy started shaking and whining. Doesn’t want to walk very far, but doesn’t seem to have a limp. Skin looks red and she’s very sleepy.

I used to walk my dog an hour without need for rest. He has started needing to stop for rest, and so I have shortened the walks. But even now he needs several rest stops of walks of just a half hour. Even when weather is cooler.

I have a highly active dog that wont stop chasing his ball unless I end it myself. At what point should I stop the play? Usually I'll throw the ball far and we'll do that for maybe an hour and when we get home he'll drink a bunch of water and then pass out. Am I overworking him? How do I tell if he's being overworked while we're playing?

I have a 2 year-old whippet and she has on occasion (only has happened 3 times and we go to the park quite often) acted very strange after running hard and fast at the off-leash park. She will be very wobbly and will pant a lot. Most recent time she couldn't jump into the back of the car and I had to lift her. It's scary to witness. But then after she drinks and rests for a short while she seems fine. I feed her the Big Country Raw dinners. She doesn't get many other treats - so basically her diet consists of meat and organs, kale and blueberries. She is very lean but I know as a breed whippets are lean.

My dog has pretty bad exercise intolerance which is weird for his age and breed. He loves to run and chase frisbees and balls but gets exhausted to the point of stumbling after a few minutes and it takes him a long time to stop panting.
