Hi, will try and give my best assessment from my own experiences.... 5 years ago, I was feeding chudleys, which my dogs thrived and did very well on... I raised two pups (Tia and Bailey) on this and grew very quickly, Tia at full height by 5 months and bordeline top end breed standard by 8months...Bailey (no relation) the same... however, I began to feed raw again when they were around the 6months mark... at this point I had a litter and raised these pups completely on raw after 8weeks. the pup I kept (Ellie) and Summer grew markedly slower, but more evenly, no growth spurts, no lanky rangieness, and did not reach expected height until around 12months....Summer never reached expected height, now at 2.5yrs is borderline under breed standard, Ellie I lost at 14months to Cancer.
Litter no. 2 raised on raw... (Kept Xanthe & Ollie) both dogs reached full height evenly & steadily...again no growth spurts, and at 10months old now, just reached full height, now filling out nicely...
Wallace has had a mix of raw and chudleys....teething gave him problems...so reverted to mushed food for a couple of months...is 5.5months and gained weight rapidly, with occassional uneven growth spurts....
Pheobe, fed raw now at 20 weeks is the skinniest, scrawniest looking specimen I have ever seen

BUT, she is now just coming into her own and filling out nicely...she is going to take much longer, possibly 18months or more....
I prefer slowly but surely...
The transfer of the older dogs from kibble to raw, showed a marked difference is coat and skin.. (never had problems) but shedding and regrowth seems more even, coat texture is better.
I cant say I have noticed any difference in nature or temperaments...all were excellent before and after...and Xanthe is wired to the moon, regardless of what I feed her...

I Now have a 5 week old litter, who are just beginning to appreciate the novelty of sucking/tossing/killing chicken wings :P
Edited to add: just remembered...before swapping Tai and Bailey to raw, I moved them onto Autarky for a while...although I dont think this would have any great effect :)
