I've started some tests with physical dog (+the tall man's finger) ,and the result is damage is the same with phys bracers+ amulet ,and with items without any elemental bonus.
Well there is something wrong with your testing, I can assure you elemental damage increases the damage of your pets. Simple test is to use a rune of fetish army of a different element than what you are wearing. For me legion of daggers hits for about 10-15m damage per hit. But because I run 80% poison damage, head hunters crit for over 25m.
ok,i did the same u said :"Simple test is to use a rune of fetish army of a different element than what you are wearing"
And there is a difference which is really small.
With 39% physical boost ,fetishes hits for 10 - 14 mil crits.
With 0% physical boost they hits for 8.8 - 12.3mil crits.
The difference looks really small,isnt it ?
I haven't looked at the math regarding adding elemental damage either, but I know that increasing Zombie Dog damage on gear and Damage to Elites is where those boosts are most noticeable. I'm betting that those are directly multiplied off the initial calculation for your base weapon damage that goes into pet melee dps. When I have added fire damage in the past for my burning gargantuan dog, I see a small difference in his burning aura and that is all. If you want a gargantuan dog to greatly increase dps, look at mods like zombie dog damage affixes.
On the subject of gargantuan burning dog aura damage, there is likely a +fire dmg threshold where it's better to focus on dog dps. In higher torment levels your dog's aura stays the same and the health of packs increases greatly, thus you are using its aura to less effect. You benefit more from his actual attacks rather than his aura when packs stop melting by standing near him.
First of all, our weapon damage is a range of damage not a solid number. So you don't realize the difference directly when just watching just because of how varied it can be, however I can assure you that elemental damage affects your let's in the exact same way it affects every other skill we have. It is a direct additive damage bonus to our damage. Your example of going from 8-10 to 10-12 is about right. I don't see an issue here.

I totally didn't take the damage range factor into account. At first glance it appeared like fire damage mods didn't make a huge impact vs. Zombie Dog damage, but they're both very similar. I'm a little unsure about Cindercoat vs. Augs chest for the 3pc bonus as to which is higher damage offensively. They're both really close, so I don't believe it really matters.
So,ill try to make a new tests ,to make the difference more visible.Maybe if i kill some boss on high torment with ,and without elemental boosts will show that difference better.
The point is to no lose base stats with the non-elemental items ,and this way we can see the difference on elemental boost more clearly.
Theres my physical FA build http://eu.battle.net/d3/en/profile/Drax-2292/hero/16506213.

Any info about that ?

There u can see the difference between 0% physical boost ,and 39% phys boost.
So,u get damage doubled because of 80% elemental boost,but i get only 10% damage boost for 39% physical bonus.
