That’s up to you. I don’t like to cull if not absolutely necessary. If she doesn’t seem to be suffering I would let her go naturally. I have one that is 7 and is acting like she’s drunk when walking. She’s eating drinking. All the usual stuff. Haven’t gotten any feed back on issue I posted.Thanks so much for the suggestions. Should she be left to live out the rest of her life, or should she be culled at some point?
