go to the vet and get the ear stiched.
I'm not sure...i know I'm not an expert on mice, but, mice are very cute and I'm pretty sure it's bad that the mouses' ear is bleeding.
Take it to the vets
A mouse's ear may be itchy and bleeding due to infections, parasites, trauma, or skin conditions. It's important to seek veterinary care to determine the exact cause and provide proper treatment to alleviate discomfort and prevent further complications.
The symptoms of ear bleeding would be blood coming from the ear or ears. Is the question more likely, "What are the causes of ear bleeding?"
Well if your ear does bleed then make sure that it doesn't get into the piercing which may cause into infection. Put pressure on the bleeding and it should stop and result in a scab. Hope this helps
You should go to the Doctor.
Well, its probably not good.
Take it to a vet. or go to a pet shop and ask them what they think you should do for it.
I think you should bring your pet mouse to the vet when its sick: running nose and or coughing hard. Bring your pet rodent to the vet if it has loss of appetite or bleeding.
Usually when a mouse ear gets crusty its because it has an ear infection or a tick (flea)
Growing an ear on a mouse involves a process called tissue engineering, where a biodegradable scaffold in the shape of an ear is implanted under the skin of the mouse. Cells taken from the mouse's own body or from another source, such as a 3D printer, are then added to the scaffold where they grow and form the ear shape. The scaffold eventually biodegrades, leaving behind a functional, biological ear on the mouse.
If blood is coming from the ear that means it an ear infection
