Blitz Update & maybe I created a monster!

First the Blitz update - he had his regular 6 mo checkup with the doggie dermatologist who is the tri-state expert on DM. Overall his condition is good, but my fear that he is losing muscle strength in his jaws was sadly confirmed. He also has a deep, nasty, non-healing wound on the joint of his left rear leg. His little body does not have the strength to fight infections so he's on yet another round of antibiotics and it has to be bandaged and redressed 2X/day. It causes him no pain for which I am grateful. I asked our vet what is the "typical undoing" of a dog with DM and he said it really varies a lot. Some lose control of their legs while others eventually cannot eat, and he said Blitz will probably fall into this category. However, if Blitz is feeling great overall and can intake food of whatever kind (we may be reduced to a healthy gruel) I do believe I will keep him going as long as he wants. As is his usual he is the Happiest Dog Alive and the vet commented that he's matured into a lovely dog with a great temperament.
As for maybe I created a monster: my dear little Moto is at the bottom of the pack and frequently gets picked on by other dogs outside of our home. After talking with my friend Laurie who offered some good pointers I began implementing a plan. One was to occasionally feed Dusty and then Moto while the others had to watch, then feed them. Other than the remaining three being confused about the change in routine this went over just fine. Second, when Moto had a bone I helped him defend it by shooing the other dogs away. Before they'd just charge him and take away his bone and he'd just let them do it. I praised Moto when he finally began to growl off stalking to-be-bone-takers. All was going fine until....
...this morning. Oh dear. This morning was the weekly Raw Egg breakfast. Moto in particular loves raw eggs, the shells are his absolute favorite. Dusty doesn't care for shells any longer so I give him Dusty's eggshells too. As usual Moto ate his special meal with great gusto but then the huge change: he began stalking the other dogs, trying to take over their food! When he approached Blitz (who takes longer to eat now) Blitz snarled over his bowl. To my absolute horror Moto's lips curled and I've never seen so many teeth or such a savage face. Honestly, for a quick second I was scared of him. Fortunately I was close and got him away from Blitz so he could finish his meal in peace.
I guess in the future once Moto finishes his food I'll put him outside to head off future conflicts. Never in all my dog-owning years have I EVER had a dog fight over food, this was the closest I've ever come.
With that said, it should be safe to say that Moto is gaining self-confidence, which in the big picture of his life is a good thing.
