Summary0007541: Dogs only scratch instead of biting
DescriptionA dog fought a giant flying squirrel in my fortress recently. When I took a look at the report, there were 4 pages of head-scratching (secondary attack) but no single bite (main attack).
Steps To ReproduceLook at dog combat reports in Fortress Mode I guess.
TagsNo tags attached.

I've noticed this too. Got one of my dogs killed when he couldn't scratch past the skin of a rattlesnake.

Might be related to the bug where people weren't using their primary weapon and punching most of the time instead, which Toady One fixed in 40.04

I think it is something skill related. The dogs may have Strike higher than their Biter skill, so they prefer the attack in which they have more skill.

What about wild animals? I have a save with it. It's night, so I can't see it directly, but it's on the other side of the river and close enough for me to get combat reports.

It works fine for most animals appereantly, but dogs do NOTHING but scratching, at least on the 8 pages of combatlogs against a downed target I examined. They are not exactly efficient, as you could guess...

After seeing a combat log of dogs biting I tested it myself in the arena:

10 out of 10 dogs without any skills always bite.
10 out of 10 dogs with skills in striking, kicking, and fighting but _NOT_ biting still always bite.
I suppose this can be closed.

I'm afraid arena combat has no bearing, we need fort-mode data:

the "conflict level" determines which attacks are used. I ran a quick test with dogs vs. horses and later lions vs. rhinoceroses. At "no quarter" and "lethal", dogs used biting (almost exclusively), at "non-lethal", "brawl" and "horseplay", dogs and lions only used scratching to attack, with no exception.

Looking through fort-mode combat logs, i quickly found a fight between a tame cougar and a grey langur. Only five or so attacks in that fight landed, but all of them (on both sides) were scratches.

Looks like the bug still exists in 0.40.24.
It might be worth checking what kinds of opponents dogs use scratching or biting against. It may be that fights between tame animals and surface wildlife never escalate to "lethal" conflict.

PS: skills don't come into it at all - dogs have no skills and learn no skills.

Yep, this is definitely some bug related to lethality levels. Skills, however, do play a major part in this bug from what I've seen. Although dogs don't use skills themselves, their bite attack still uses the BITE skill. If you remove that from the dog's bite attack - they'll bite away at non-lethal levels of fighting and lower (although the intensity at which they fight seems to die down as the lethality decreases).

My guess is that skills are tied with certain levels of combat - and biting is considered a lethal attack. Chances are encounters with different scenarios (war animal vs wildlife, invader, hostile creature, etc.) are at different levels of lethality, and cause the dogs to not use their bite attack.

after some research in my own fort, War dogs when attacking wildlife will result in scratching. however hunting dogs attacking wildlife will literally rip their guts out. http://imgur.com/gallery/bjJC6 [^] , it seems that only hunting dogs will actually use their main attack on wildlife.

Hunting dogs technically do not have to adhere to [KILL_NEUTRAL:ONLY_IF_SANCTIONED] that non-military dwarves enacting self defence vs large predators targeting them do since hunting overrides it and allows lethal attacks.

Relevant to 0010059 where wild animals & tame animals (including semi-sentients) all adhere to site ethic rules. Wild animals on 'Acceptable' or 'Required' site kill neutral ethics use lethal attacks fine.
