Manic behavior

I agree with Karen. I'd ask your vet about the possibility of a psychomotor seizure. Toxins building up in the liver might also be a possibility.

I have a GSP and a GWP, The GSP has allergies to everything and can only be fed fish and rice, she also has a hole in heart. I have to keep her weight down and her fitness high. She is quite small and with the amount of activity to keep her fit she takes a lot of feeding! I feed her three times a day just to get enough food into her without overloading her tummy. If she drinks straight after eating she is often sick as her tummy can't cope with the volume, so I feed a small meal in the morning, a small meal at lunchtime and a big meal in the evening that has been soaked in warm water for at least 20 minutes.
The Wire Haired can, and will, eat anything - I have seen him climb trees to get the remains of buzzard kills! He will usually pass things that don't agree with him in a smelly runny mess but has, on occasion been sick. Pointers, especially German Pointers tend to have fairly delicate tummies although their tastes are not!
My Wire Haired also can get stuck on licking shoes, furniture, the other dog, a wall . . . whatever, but does not seem connected to any sickness. He is a grass eater too and needs to be distracted from it sometimes. Maybe your dog is eating stuff when out walking (my GWP can remember where a pigeon has died or a cat has had a poop for weeks!) that you don't see or maybe it is just being a Pointer (aren't they brilliant?) or maybe it is showing signs of allergy. You also need to make sure that along with exercise the dog is getting enough mental stimulation, working dogs need to work. Hope that gives you some ideas.
