You said the dog was diagnosed with a lipoma so I’m assuming the vet did a fine needle aspiration? There are some fatty growths that may be cancerous but a true lipoma isn’t so don’t panic. They’re very common, most vets don’t even bother to remove them unless they’re in an awkward place and causing trouble. For example, under the “armpit” and causing mobility issues. It will most likely continue to grow. Wouldn’t hurt to slim the dog down if it’s overweight but other than that, don’t worry about it.
