Being in heat can cause behavioural changes in dogs, as long as they are not too extreme and the dog is otherwise well I would not worry too much. Quite often when in heat dogs well be lethargic and not want to eat very much.

    I am sorry to hear about your dog. If you feel she is lethargic and acting sick I would recommend a visit to the vet to have her examined. Usually dogs in heat are actually more active than they are otherwise, so I would be concerned something else is going on with her.
