As for the NILIF training, I had to look it up as I was not familuar with the term, I do kinda train like that automatically, just never knew there was a name for it.
I hope those ideas will help.
DO you work with him when he's a tad hungry, like near dinner time or breakfast time? Sometimes that helps. Make sure the treats are tiny...pea sized. That's all they need and then they won't get too fat, or cut back a tad with their food. (eh-hem...just took Lyric to get weighed...vet said hes got love handles and can't feel his ribs. 113LB!!!! should be about 93....Woops! I never saw it coming. He looks so handsome and he's my perfect angel so how could anything be flawed? ROFLOL! So, he's on a diet.)
Ok...here's a yummy treat recipie:
Your dog will jump through hoops for these.
1 container of chicken livers
1 egg
Puree in blender
Pour into mixing bowl and add 2 cups of oat flour (if you have it or regular flour)
Mix well and pour into greased 8x8 baking pan.
(I sprinkle a little fresh parmessan on top)
Bake in pre-heated 350 degree oven for about 1/2 hour or until sides pull away from edges of pan.
Cut into as tiny pieces as your wrists can take and cool. You can freeze some in baggies for later. Let your dog lick the pan and spoons when cool.
