Dog breeds and extinction after collapse

[Dawdler]

You realize that statement makes no sense. The next generation after the 1st would have the 1st as parents. Given that you would see hybrid vigor in the first hybridization, you can't say "even worse" because the hybrids are better. Did you mean relative to the grandparents? If so, the argument is not that simple. It depends on if one is still outcrossing, backcrossing, etc... Also you have to define the measurements used to determine "worse". It's a complex argument that can't be easily reduced to simple generalities as is usually seen in the first hybrid generation.

You don't realize or understand that you can't cheat biology.
Hybrid vigor exists because genes for growth etc. are being duplicated and not inactivated. Best examples are ligers that have no limit to growth and they die because of it. They are bigger than parents and yet they can't get their dick up and make viable offspring.

Let me dumb this down for you:
Parent: F1 M1 (OG parents that aren't gay)
Offspring: H1 H2 H3 H4 (Hybrid litter)
We introduce new dogs F2 and M2
Offspring with: H1F2 or H2M2 will always be weaker than H1 or H2 or even F1 or M1.

Hybrid vigor lasts for ONE generation only. That's why we use it for our crops and we don't reuse the seeds from the harvest.
Everything abnormal is abhored by nature.
Size of animals is determined by food availability and not magic.
Hybrids suffer from lot of health issues due to overgrowth of their basic biological functions - heart failures, back problems and so on.

Based on firsthand experience, the Australian cattledog (please don't confuse with the Australian Shep) is a robust livestock guard breed in a small resource-efficient package. They have stamina for days, are eminently trainable if you start at an appropriate age, consume less food than larger breeds, and have the proper drive to be trusted with rounding and protection tasks even in absence of a handler.


Mine have gone above and beyond to repel predatory threats as large as black bear, often when I was away from home and my herd of goats would have otherwise been vulnerable. I've had several and they've all been healthy, hardy, and easily put on task. Yes; a larger breed would have more combative capacity. But they also require pounds more of feed a week compared to the cattledog, which is a very important concern when I have to potentially supply nutrition for myself and every living animal in my care.

Cattle dogs are incredible; loyal, and intelligent. They will absolutely fuck up a person if they threaten their owner as well.
I'd also add Malinois to the list.

Any police dog. German Shepards, Belgian Malinois, even Poodles if we're getting desperate.

The smarter, the better. Trainability, especially in regards to self-defense, would be an incredibly important factor that's worth preserving. Not going to touch on purebred health issues here because at this point I don't think you can find many purebreeds without crippling health issues and mutts are a whole different bag of issues, but assuming that all the dogs were as healthy as possible I'd go for these guys 100%.

Additional shoutouts to most herding dogs for being invaluable on farms and generally very smart.

Something tells me a lot of pitbulls will get shot on sight the second the power goes out.

counterpoint: if you had a toddler-mauler at your disposal and a desire for power in a world where might makes right, why would you ever let anyone touch those things? Especially given the demographics of pitbull owners, I fear there would only be more of them after the collapse lol. Mastiffs too, but I doubt they're as easy to come by so maybe not?
