1. Once a moocher, always a moocher.
Once you reward begging behavior with something off your plate, you can expect to see the same hopeful eyes looking up at you every meal from that day forward. That's fine if you don't mind, but if you have a dog that whines, her behavior may disrupt your dinner. If you do mind your pet's presence, you'll have a hard time training her to stay out of the room now that she knows she just might get a handout. Also, some dinner guests don't appreciate a tongue-wagging dog at their elbow while they try to eat their meal.
2. Table scraps don't offer the nutrition pets need.
3. Table scraps are the quickest route to weight problems.
4. Table scraps are a leading cause of digestive disorders.
5. You could end up with a finicky eater.
6. You may create a thief.
7. Treats are a better choice.
Pet treats, however, are usually more nutritious and tend to have far fewer calories than most table scraps. There are other benefits too, depending on the type of treat you buy. Biscuit-type treats are good for your pet's teeth as they help scrape off plaque and tartar that can cause dental problems. Rawhide satisfies a dog's urge to chew, relieves boredom, and is also good for teeth.
Treats also don't encourage bad behavior. In fact, it's usually the opposite. Many people use treats in training to reward positive behavior.
As with anything in life, treats should be used in moderation. Too many treats can add weight and affect your dog's meals. As a rule, treats should never account for more than 10% of your pet's food intake.
