Taking your Pointer into some shallow water, such as a shallow section of a river, and having them retrieve objects can be a fulfilling activity. If you do not hunt with your dog, rather than using pigeons or other birds to practice, you can use a scented toy. Family companion dogs that enjoy retrieving may also like a Frisbee or ball. If you do use your Pointer for hunting, then, yes, there are birds you can get from a hunting or outdoor store. If you have a Pointer and do not hunt with them or only hunt occasionally, it is important to keep your dog very active with exercises that provide mental and physical stimulation. Water retrieval is one of those activities!
The Kong is a hard, rubberized toy for dogs. It comes in different sizes. Choose a medium to large Kong for your Pointer and add dog-safe peanut butter or cheese to the middle (the hollow area). This toy can provide a great deal of enjoyment and mental stimulation for your dog as they work on removing the treat.
Tug of War is a classic and fun game for you and your Pointer to play together. Use a tug of war rope toy, which can be purchased at a pet store, and pull away! Be sure not to tug too hard; you can judge the tension needed by your dog's pull. Have fun!
