Is it possible to have more than 4 Zombie Dogs?
I believe some answers here are outdated, and with my personal knowledge I believe the upper limit is at least six:
- Default limit is 3
- Zombie Handler passive gives you +1
- Midnight Feast passive gives you +1
- Fierce Loyalty passive gives you +1
This would be a total of 6.
The Witch Doctor has several ways to get Zombie dogs even if they don't have the "Summon Zombie Dogs" Skill. The limit of 3 (or 4, with the talent) is just a built-in property of the class.
It doesn't matter how you get them, but the maximum is 3+1 dogs every way you look at it.
