Does Teaching Stack with Old Dog?

[halcyan2]

Teaching says "does not stack" so it obviously doesn't stack with multiple teachers.

Old Dog says "does not stack" so it obviously doesn't stack with multiple old dogs.

But does Teaching stack with Old Dog? Or are they considered the same 10% bonus and so they don't stack with each other?

I had the same question a while ago and I have tested it. When you have for example Len with Old Dog and Teaching you get more EXP then only have 1 Teacher, it works. I have tested it on Ernie Island, one time with MD (Teaching) and then changed him with Len (Old Dog and Teaching) and it was more XP for everybody with Len. This means XP from Teaching and Old Dog stack :)
