Why is my 2-year-old unspayed dog whining and sleeping in mud?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed | Female | unspayed | 1 year and 10 months old

My dog is about 2 years. Lately she's acting different. At 1st because of her growing breasts,mood swings and age I thought she might have her 1st heat soon.But now she whines a lot and sleeps in mud all day! I'm not understanding her behavior.(she's not pregnant)

If Spoty isn't spayed but showed signs of pregnancy (weight gain, swelling of the mammary glands, nesting behavior, etc) it's possible there could be a phantom pregnancy going on, or even something else related to the reproductive tract such as an infection. Having her examined by a vet if you haven't already is a good idea to rule out any hormonal or reproductive issues, as well as any other underlying issues such as illness or injury causing her behavior. If you're in an area that is extremely hot, it may also be that Spoty is trying to cool off by laying in the mud. Extreme heat can make a dog more tired and lethargic, however if the temperature hasn't been too high or you're seeing other signs of illness, seeking vet care is best.
