Please contact your vet or an emergency animal hospital as soon as possible. They will be able to diagnose the cause of the engorgement and provide appropriate treatment.
Possible causes of engorgement in dogs can include:
* Tick bite: Ticks can inject toxins that cause localized swelling.
* Allergic reaction: Allergies to insect bites, food, or other allergens can cause swelling.
* Infection: Bacterial or fungal infections can lead to inflammation and swelling.
* Trauma: A wound or injury can cause swelling and inflammation.
* Cancer: In some cases, engorgement can be a sign of cancer.
It's important to note that home remedies are not appropriate for treating engorged dogs. Please seek professional veterinary care immediately.
