Gorgeous Border Collie Cross

I’m currently trying to rehome my gorgeous Border Collie X Beagle. Her name is Mici (Missy), she’s desexed, and she has the loveliest nature, very energetic, her favourite thing in life is fetch (it’s not a game, she takes it very seriously haha). She needs someone active because even though she’s nine-years-old, the border collie in her is strong, and she needs at least one walk a day preferably coupled with a decent game of fetch. She loves the beach and parks. We currently already have two dogs at my residence, and took on Mici to help a work friend out, however three dogs is just a bit much for our family, especially with Mici’s needs. I have all the paperwork for her as well as collars, leads, a seatbelt and harness, etc.
