We want an idea of how big he will get and what he may look like.
We just wonder if he will be more than 50 lbs, that is the largest our landlord will allow.
Unfortunately, with mixed breeds, you have no idea what to expect. It's just not predictable at all. The best thing you can do is to find a mixed breed of smaller sized dogs in general, rather than a large/medium and a small together, where the pup could take on either size or some where in the middle.
