My dogs had this huge bump on her head for a few months now. Initially started as pea size.
She doesn't act any differently and shows no signs of pain whatsoever. If anything she tries to scratch it sometimes if there's air blown on it.
I plan on taking her to a vet this week.
How hard is it? I'm not a vet or anything, but from the picture it looks as if it's just a cyst, or some other type of growth. If so you don't have to worry much, but it is a good idea to take her to the vet in case it's cancerous.
>not taking your dog to the vet when theres a huge lump like that
Also i think your dog has bigger problems than a lump
My friend's Kerry Blue Terrier had a growth just like it. Ended up just being a non-cancerous growth that's common for their breed.
You can either take the dog to the vet and have it removed, and/or leave it alone. But since it's growing, it'd say the ethical solution is to have it surgically removed.
