Dog biscuit is a snack  that is used as a supplement for dogs
I give my dogs biscuit sometimes. How healthy are dog treats though? 
Judging by the fact that they are always well made, and  tend to be hard and dry, I would say they are healthy
I guess that makes sense. What other supplements exist to give to your dog? 
I'm not too sure but I like dog biscuits because  they come in a flat bone-shape.
Yes the little bone shape is actually pretty cute. My dog gets so excited to get them. What are dog biscuits even made of though?
You won't believe it if I tell you that some manufacturers of the biscuit thinks  clean the dog's teeth, promoting oral health.
