"False heat" in dogs usually refers to a silent heat, where a female dog cycles (ovulates and is fertile) without the typical visible signs like bleeding or swelling, allowing her to get pregnant unnoticed; or false pregnancy (pseudocyesis), where hormonal shifts after a normal or silent heat cause a dog to act pregnant (nesting, milk production) even though she isn't, notes VCA Animal Hospitals and PetHelpful. Both can be confusing, but silent heats mean fertility, while false pregnancies are a hormonal mimicry of pregnancy after a heat, with spaying often recommended for prevention.

How do you know if your dog is having a false heat?

What can be mistaken for pyometra in dogs?

Pyometra in dogs can be mistaken for Urinary Tract Infections (UTIs), gastrointestinal issues (vomiting/diarrhea), and even pregnancy, as symptoms like lethargy, loss of appetite, increased thirst/urination, and abdominal swelling overlap, but a key differentiator is the presence of vaginal discharge or a history of being unspayed a few weeks after heat. Other conditions with similar signs include metritis, uterine torsion, or even uterine cancer, requiring a vet's ultrasound and diagnostics to differentiate from fluid-filled uterus (hydrometra/mucometra) or pregnancy.
