It may be a benign growth, but I cannot make a diagnosis without seeing him in person. There is always a chance any lump could be malignant in dogs. Any suspicious lumps should be examined by the vet. The vet can perform a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the lump to get a sample of its cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. Once the cause of the lump is diagnosed, the vet can discuss treatment options if needed. Give his vet a call to make him an appointment.

This bump has been on my Labs neck for about 4 months, doesn’t seem to cause his discomfort unless I try to touch it. It has been growing
This lump on Max could be a cyst, a benign tumor, or a malignant tumor. It is concerning that it has been growing, and this is definitely something that needs to be seen by a vet.

My 11yr old lab mix has a mass larger then my fist on his side. It had soft fluid for a while now hard and getting larger. It doesnt bother him. Should i have him see a vet
This could be a seroma from an injury, a cyst, abscess or a tumor. Cysts and abscesses need to be drained by a vet. If your vet suspects a tumor, he will do a fine needle aspirate to determine whether it is a harmless lipoma, which does not need to be removed unless it is ulcerating or bothers the dog due to its location or size, or another tumor that needs to be removed. Please make an appointment with your veterinarian for an exam of the mass.

Hi, I had noticed a rather large (10 p) sized raised lump on my 10 year old Labradoodle's right hip. As a vet what would be your next steps to examine this? Thank you very much in advance! Heidi
Thank you for submitting your question regarding your dog. I recommend that you see a veterinarian. I will typically perform a procedure known as a fine needle aspirate when a dog develops a new bump. I use a small needle to collect a sample of cells to evaluate under the microscope. This helps me to diagnose the bump. It could be a benign growth that does not require treatment, a cancerous tumor that needs surgical removal or even an infection under the skin such as an abscess. I hope this information helps!

Yes, I would be concerned. Without seeing a vet, you can't know for sure if this lump is a lipoma. In a 10 year old dog, there is always a concern that any lump could be malignant. Any suspicious lumps should be examined by the vet. The vet can perform a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the lump to get a sample of its cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. Once the cause of the lump is diagnosed, the vet can discuss treatment options if needed. I would call the vet today to make an appointment for him to be seen. I hope this helps!
