I'd say the vet knew little about breeding.
Bitches will have a hormonal moult; after having a litter (virtually to the skin).
This is usually not until about weaning, though maybe the hot weather is hurrying things along. My girl is also loosing hers in clumps down to the skin (perfectly normal) and it is rather sooner than usually, as pups only 5 weeks old, and she started at least a week ago.
