My spayed girl is driving unneutered males "crazy with love"

That’s quite strange; I’ve heard of neutered males getting pestered by intact males before. Some neutered dogs apparently smell like a ***** in season, basically. But I’ve never heard of similar stories regarding females. Are you absolutely sure your dog was spayed properly? It’s quite rare, but sometimes a spay can be "partial" (or unsuccessful), meaning the female goes into season without us noticing, but other dogs can definitely smell it. This happened to my parents with their cat. She was supposed to be spayed, but there was a constant parade of tomcats hanging around her. After a vet visit, it turned out the spay had "failed"—a tiny bit of ovary had been left behind. She was going into heat, which was imperceptible to us humans (especially as we thought she’d been "done"), but the local toms could certainly tell! She could have even had a litter! Luckily, we realised what was going on in time. A failed spay is pretty rare, but it does happen. Bitches usually come into season twice a year, so if the timing seems to match up, it might be worth asking your vet what they think.

I find that a bit strange. My girl was spayed when she was around 9 or 10 (due to pyometra), and no dog ever had the cheek to get too close to her, neither before nor after. It’s always Her Ladyship who decides what distance other dogs should keep, and woe betide them if they try to cross her boundaries, lol.
