Not counting training treats (which are generally charlie bears nowadays), our girls get several little treats several times a day.
Most treats are either charlie bears or Old Mother Hubbard Small Biscuits. They randomly get a treat when they kennel when they are left home in the morning and at noon. They also get treats when the mail comes in because our mailman leaves them treats with the mail (he's a dog-friendly mail carrier!).
They also generally get a special treat in the evenings, such as a spoonful of pumpkin. They eat once at day (at noon) so they enjoy a little extra in the evenings. We also use carrots. They like ice cubes, as well, when they come in from playing outside.
Now, these are "approved" treats. The girls also get contraband treats from DH at EVERY MEAL!! He literally saves the last bite of whatever he's eating and then divides it into thirds and treats the girls. Can you believe it?! It's terrible!!
