My Schnauzer has high ALP. Is it related to her head fibroma?

Updated On September 23rd, 2025

Pet's info: Dog | Miniature Schnauzer | Female | spayed | 15 years and 3 months old | 13 lbs

My 11 year old mini Schnauzer had an extremely high alkaline phosphatase at 2000 U/L so we are a bit worried. She had surgery recently for a benign lump near her spleen but now she seems fine, except for a growing fibroma on her head. She has been eating high quality Hill's Mature Light Mini dry food with chicken for many years now so her diet is stable. Do you think there might be a relation with the fibroma and do you think there would be a risk to have it removed (surgery w/ anaesthetic)?

First, I would want to get to the bottom of why Zoe's ALP is so high. This may be indicative of a hormonal disease like Cushing's (overactive adrenal glands) and if she has any of the symptoms, such as increased thirst, increased urination, panting, increased appetite, or a big belly, it's worth it to consider ruling out Cushing's disease. An abdominal ultrasound may be helpful in this quest, as it will show changes to the liver as well. If you are sure the mass is benign, I'm not sure I would even remove it, unless it's bothering her. It's hard to tell based on the pictures and without something for scale, but it seems small and I would consider talking to your vet about whether it could be removed with just some local anesthetic instead of general anesthesia.
