This may be an impossible request. I'm looking for recipes or ideas for puppy training treats that contain no grains, sugars, salts, dairy. Just meat, maybe eggs. I found one for liver but I'd like to create a variety & I'm aware that too much liver is not good.
For those that may be interested, this is the liver recipe that I found:

Liver Treats Liver Treats
* fresh liver
* water
* paper towels
* small freezer bags

Step1
Add fresh liver to water which is at a full boil. You may add salt to this water if you wish. Allow to cook until liver is no longer pink. Usually about 5 minutes.
Step2
Remove liver from the water and promptly rinse with cold water under the sink tap; all the while gently rubbing at the liver to remove any slime or white foamy stuff that may be on the liver.
Step3
Pat the liver with paper towels until dry.
Step4
Place liver on a cookie sheet and insert into a pre-heated 200 degree oven until it takes on a leathery appearance and feel. The liver should not crumble or break when picked up. This should take approximately 20 minutes.
Step5
Once cooled, cut liver up into bite sized pieces.
This treat stores well in the freezer

I use dehydrated chicken breast bits or turkey tenderloin bits

Sometimes we can get really thin sliced palomia steak at a great price, so we just cut it intosmall pieces and dehydrate that on low heat in our convection oven. They work great!

i just bake liver on low heat to dehydrate it. It just stinks up the house so I do a giant batch in one day and then freeze a lot.

i'd imagine that if you cut it or rolled it out flat enough, you could dehydrate just about any meat.

however, meat stinks, so i dehydrate sweet potatoes with a little bit of cinnamon on them in the oven. smells really good and rowdy loves them. dunno about the sugar content in sweet potatoes though.

I used to make biscuits.
boil any meat or organ meat
remove from water and puree it
Add eggs
Add enough garbanzo bean flour to make a stiff dough
you can roll and cut out or just pinch off pieces, roll balls and flatten out like cookies, any size you prefer
Place on cookie sheet and bake til browned @ lowest temp of oven
When browned baste with liquid from cooked meat, turn and baste other side
Return to oven and cook til dry and hard OR
you can place in dehydrator at this point to finish drying and hardening
