Slick, I hope that the vitamin B12 shots will help Max. Both my RB Starr and Ziggy have had them and I injected them myself at home and they got them once weekly. It gave Starr lots of energy and helped his dull coat and improved his whiskers. It helped to improve Ziggy's appetite.

Since Max is still having problems using the litter boxes, you might want to buy some puppy training pads for him. You can just put them in the places where he's been going potty and hopefully he'll learn to use them so then there won't be a mess for you to clean up. You could also put them near the litter boxes too. Good luck.

Lots more prayers and positive thoughts are being sent his way. Please take care. (((HUGS)))
