<human>: Provide a brief overview of the text.

Ok so let em explain a little, because I'm sure that might have been a little confusing.

I have a blue heeler, roughly about 3 years old. If he had a choice he would chew till he died. During meal times (because I have young children and I dont want him eating the food they 'give' him also begging drives me CRAZY) I have him go to his bed until I call him back in to eat whats fallen on the floor. I'm kind of looking for a treat I can make at home, that has something of a lasting power. By that I mean this boy has some intense jaw muscles. I can't leave him with a tennis ball, ten minutes and its in pieces. Rawhides he eats so quickly he gets sick. So far the only 'treat' or chew toy I've been able to make last are those nylabones.. buuuut I'm pretty sure they are plastic and hes actually tearing them up and it makes me nervous. Got any recipes or ideas of things I can make at home that he CANT just swallow and may take him a second to chew that I can give him during our meal times?
<bot>: My dog chews everything to death, I want a recipe that creates a nice treat that will take him a minute to get through while we eat our meals.
