The reason why dogs don’t eat during their menstrual period is because they are in estrus. The dog will show poor energy and loss of appetite. At this time, the owner can prepare more light and easy-to-digest food for the dog, or give the dog some normal food. Like to eat food, this situation will recover when the dog's estrus is over.

Tip:

The dog’s menstrual period is the estrus period. At this time, you can help the dog find male dogs of the same breed for mating.
