I thought you might all like to see my rescue Toby's transformation we adopted him 6 months ago (surrender pic on left) and look at him now (recent pic on right)!! What a difference.

His coat and eyes shine, he went from nearly 11kg to 8.8kg, he plays with toys, he is bright, and even though struggles a lot with his baggage and emotional issues, he has come a long way behaviorally too...all with the help of a great diet, proper supplements for his issues, a Delta certified positive reinforcement trainer and lots of love!
Sure, he will probably never be a lover of dog parks or other dogs (except Brooky!) in general...but he is happy for human love despite his horrible past and he can retire on my couch forever as far as I'm concerned
