My 8 year old yellow lab developed an egg sized lump under her chin. I took her to the vet and he said it was a blocked salivary gland. It was lanced and she was put on antibiotics and steroids. She had a speedy recovery. It is now three weeks later and the lump has returned. She is eating and drinking and does not seem to be in pain. I took her to the vet and wanted them to try medication (rather than going through with lancing again) to see if it would help get rid of the lump or at least shrink it. The vet prescribed tetracycline. Any advice or information would be appreciated.
