Customer Question

My dog developed a large knot on his hip very suddenly about the size of an egg. He doesn't seem to have any pain from it but it has been there for several weeks now. Any ideas?

Hi there,

I'mCustomerand I would be glad to answer your question about Marilyn Irwin. The fact that the "knot" has been present for several weeks suggest that it is not the result of any trauma (i.e. inflammation) but that it is a tumor of some sort (i.e. benign or malignant). A visit to your vet is in order to have the area evaluated. Sometimes the vet can take a small needle and collect some cells from the site to learn if this is something that requires more attention (i.e. surgical removal). If a fine needle aspirate is not helpful in identifying the nature of the mass, then you will have the option of observing it to see if it changes in size or character (i.e. becomes bothersome to your dog) or being more aggressive and having the area surgically biopsied or completely removed to make sure this isn't cancer. Since Marilyn Irwin is an older Boston Terrier, I would aire on the side of caution and, if you can't discern the site is benign with fine needle aspiration, then I would recommend a biopsy of the tissue under anesthesia at a minimum. Boston's seem prone to cancer more than some other breeds: especially mast cell tumors.

I have had 2 other knots removed in the past 5 years and both were not cancer. Does that indicate to you this one is the same?

No, unfortunately each growth must be evaluated on an individual basis. They are very often different types of tumors and can require very different treatment approaches.

Ok thank you very much

You're welcome. Best of luck to Marilyn Irwin: I hope this growth is benign too!
