Going though piles of info on organic fertilizers for lawns. Web
pages, newsgroups, mag's etc. etc. Looking for some current opinions
on this. I'm searching for a slow release fertilizer for grasses that
is completely non-toxic to domestic animals (dogs, cats). I have
about 3 acres of grass that has been hit heavily by an enduring
droughts for the past 4 years on the Canadian prairie. I've raked
some of the worst sections . . . . added peat, sheep manure and
heavily overseeded. Looking for recommendations on a good strategy.

Sounds like you are taking the appropriate steps to rejuvenate your lawn.
I'd consider investing in a mulching mower - recycled mower clippings
("grasscycling") is the easiest and by far the least chemical method of
fertilizing your lawn.
