Are small dogs ok?

There is a separate enclosed area for smaller dogs (<25 lbs I believe). There are enclosed areas where its usually less busy as well. Nevertheless, if your small pup is social and has no issues with larger dogs, trails and ponds are great places to walk as well.

Yes, there is a separate fenced-in area only for small dogs.

Depends how small, there are larger dogs there but some smaller as well. If your dog is social and not timid, you should be fine.
