Does A Female Shih Tzu Vagina Protrude, Or What Does A Hernia Look Like On A Dog?

You have not mentioned which hernia you are looking for? There are three types of hernias in dogs.

1. Inguinal hernia
2. Umbilical hernia
3. Diaphragmatic hernia

I assume you are asking about Inguinal hernia. It is recognized by soft mass in the groin area. It signs are

• A sac in groin area which is warm to touch
• Abdominal pain
• vomiting
• Loss of appetite.
