I'm getting multiple wolves in Minecraft without taming them?

So with the new update 0.9.0 in Minecraft PE I was able to tame wolves. So I found a pack of wolves and I tamed one. Then one Minecraft day later I had two wolves following me around. That was weird because I only tamed one wolf. Then 2 Minecraft days later I found some clay in some water I got some clay then I left. I came back to see if I had missed some clay and a wolf was sitting by the water. I thought I made one of my wolves sit down and forgot about him but then I saw I had three wolves. Can someone tell me what's going on?

It is probably just glitching out because non-tamed wolves shouldn't follow you i have never had that problem but it definitely is a glitch because only tamed wolves act behaved or follow you.
