thats smart!
breed definatly plays a part, and labs are a hunting/retreiving breed....
sometimes instinct is stronger than training and while most wouldnt mean to hurt, play often leads to death when play is a larger dog with a flappy noisy hen!
(i feel the same way about leaving dogs of any size with kids...its jsut not smart... lol)
i also know what you mean about the dog being nessicary...
my chinese crested are not officially service dogs, my female is acting as right now, she alerts to seizures and responds as best she can she also helps defray attacks, disrupts my ocd ect...
unfortunatly shes not large enough to do many of the tasks i realy require from a service dog, but right now she is my life line. more than that though is my pets are the reason i am alive, i suffer from severe bipolar depression and on a down suicidal thoughts are not uncommon...my dogs aremy reason not to act on that, as selfish as it sounds, i love my family but know theyd survive if i wernt here...my dogs though, my male especially would fret so much that hed probably stres himself to death.
it sounds like this pup ha had a similar effect on your son...while the help isnt 100% there yet, that young pup has already made a difference. for some dogs are pets...for others they are working animals...
for people like myself, they are a tether to reality a reason to live...a nessecity in living form.
if tshf, my animals care does become a neseccity...because wthout them im not sure i could mentally survive...
as someone else pointed out, on raw and pretty much any none comercial diet, the dog will eat MUCH less,
a general rule of thumb with raw feeding (probably different for cooked but i cant see it being much different) is a normal energy level adult pet dog should be eating 2-3% of their ideal body weight a day...
so a 60lb adult lab will only be eating about 1 1/2 lbs of food a day. (now again thats raw feeding amounts so that weight includes bone in.
id say cooked for an adult lab would be mabe 2 cups a day?!
dogs working in the feild (ie farm dogs) or performance dogs will usually need more, and puppies do need alot more (as much as 10% of their current weight while growing) but once a dog hits its adult hood, the amount of GOOD food needed drops, we have to feed so much comercial kibble simply because most of it is fillers, stuff the dog cant digest, we feed more of it to get them enough good stuff...
the better the food the less they eat and the less the body wastes (youd be amazed at the difference in poop between a kibble fed dog (even the realy good kibble) and the poop of a raw fed dog lol.
so in the long run, home made cooked and home made raw tends to be cheaper than even the cheapest of the comercial kibbles, even more so if you can raise your own meat.
you asked about quail and how long untill butcher.
itll depnd on the type of quail, i like cortinux, but if done right quail is incredibly economical as a meat source.
male cortinux are ready for the table at 6-8 weeks of age and a female will typically begin laying before shes 2 months of age and lay almost daily for a year beore production grows. (and since dogs dont care if thier meat is tough or gamey, theyll happily take "retired" layers old roos and otherwse "inedible" meats lol.
i would definatly look into cortinux, they are much more efficient layers per lb of feed than even the best producion chickens (about 5 quail eggs to 1 chicken egg size wise for baking, but a chickenn needs about 3 lbs of feed to make about 1 lb of eggs...cortinux about 1 1/2 lbs of feed per 1 lb of eggs...
and they take up much less space

they breed readily, typically hatch well
rabbits are also wonderfull meat animals, easy to raise (raise em in wire floored tractors so they get fresh grass for an even more economical way) they breed like crazy, VERY easy to process, and its one of the healthiest meats available!, plus use the pelts for blankets, adding fur for warmth in the winter, general craft projects and such.

in terms of serving, i always give my dogs their meat de-skinned and beheaded...its much less messy and the skins (ie rabbit) can be used for better uses than being wasted.
the guy i get my raw from donates the heads to a raptor rehab center...
