Unfortunately my dog now has no manners because he loves this food so much!
When my German Shepherd was a pup we had tried him on JWB, and he didn't seem fussed. We quickly switched to another brand but recently (he's now 17 months) decided to try out the Large Breed Adult Lamb.
He goes crazy for it. Normally he will sit and stay whilst we scoop some food out for the cupboard and he waits for the signal. For the first few days he could barely sit still he was so excited. He's calmed down a bit now but seems very eager to eat the food. The pieces are very big, which make scooping a bit difficult but he seems to enjoy eating it - much better for him I think than the tiny nibbles he was used to before!
