My Chihuahua has a head lump. Is surgery safe? What are the risks?

Updated On September 23rd, 2025

Pet's info: Dog | Chihuahua | Male | neutered | 11 years old | 5.5 lbs

Hello, My 5 lbs Chihuahua had a small mass, like the size of a pea prominent on top of his skull, my vet suggested to hv it removed & do biopsy. Isn't it a minor surgery as told by my vet? Will it affected the well being of my dog after the surgery? Any disadvantage of the surgery? I am so worried of whether to hv the surgery or not,! The mass doesn't affected my dog at the moment, blood & urine test done, everything fine, my dig is just as happy & healthy as normal now! Thanks for yr opinion!

If the mass has changed in size, colour or texture then yes, removal and biopsy is recommended immediately. If not, you could opt to monitor closely but be cautious it may change quickly and become difficult to remove or he may develop other complicating factors such as kidney disease or other conditions which may make anaesthetic less safe than it is at the moment. Biopsy of a small mass is a minor procedure with minimal risk of complications other than the small risk which accompanies all anaesthetics
