We have a chocolate lab and she has a love for dog biscuits! She ran out one day last week and I've been wanting to try my hand at making them for a long time, so this was the push I needed.
I used this recipe for Basic Dog Treats. I didn't have any chicken broth on hand, so made mine with bouillon, however I doubled the usual proportions to make it extra rich (ex: instead of 1 tsp. per 1 c. water, I put 1 tsp. per 1/2 c. water). She LOVES these - she stands at the door and begs for one.
They were very simple to make - I used my Kitchen Aid mixer to whip up the dough and didn't even need a rolling pin, I just flattened it out with my hands. I had some bone shaped cookie cutters - but they are a casualty of letting Emily play with the cookie cutters so much! So, I just used a circle and diamond.
As far as cost, I think it would work out to be about the same as buying them on sale. But, it was a great feeling to know I could do it and she loved them!
