There are a few things to keep in mind when training a dog that is not food motivated. First, it is important to find something that your dog is motivated by. This could be a toy, praise, or even just attention. Once you have found what motivates your dog, use this as a reward for good behavior. For example, if your dog is motivated by attention, give him a pat and a verbal cue when he does something you ask. If your dog is motivated by a toy, let him play with the toy after he completes a task. Keep in mind that it may take some trial and error to find what motivates your dog. Be patient and keep trying different things until you find something that works.
Another important thing to remember when training a dog that is not food motivated is to keep sessions short and sweet. If your dog is not interested in treats, he is likely to get bored quickly. Therefore, it is important to keep training sessions short and focused on one task at a time. Once your dog has mastered a task, you can move on to something else. If you try to do too much at once, your dog is likely to get overwhelmed and lose interest.
Finally, be sure to end each training session on a positive note. This will help your dog associate training with something positive and enjoyable. If possible, let your dog have a play session or his favorite toy as a reward for a job well done. With patience and perseverance, you can train a dog that is not food motivated. Just remember to find what motivates him and keep sessions short and sweet.
