It does sound as if the hedgehog madness has contributed to her lassitude plus the hot weather. Hope it is that, she odes sound ok a the moment if she is eating and drinking well.
Awww, she is a fluffy little job isn't she? Apart from the hedgehog, I'm sure this constant heat has taken it's toll on our dogs. Let's face it, most of the time - in our area, South West England - it's windy and cool. This year is exceptional.
Even our Molly, a 2 year old very active lab has struggled.
Fingers crossed little Nelly for getting your mojo back x
