Invisible wolves and tamed dogs no matter what options I choose in the video settings

Ok, I logged into Minecraft thinking, "oh, I'll bump up my render distance" so i did and things started glitching out (eg: mountains overlapping each other but weren't actually there.) so I turned my render distance back to what i usually had and it was fine, until i went to my tamed wolves. I found them still tied to their leads and i could see their circular shadows but, couldn't actually see them. I could also hear them, just not see them. I also went into creative mod and spawned a untamed wolf in front of me and it was invisible too so I ask you; is there a way to fix this? If not I'll just live with invisible dogs and 5 chunks for render distance.
