I noticed this hard pimple like bump on my dogs upper back about 6 months ago and it’s still there. She has another smaller one in her hip area as well. She is 3 years old in August so she is still very young to have bumps. however she saw a vet a few weeks ago and they told me it could be a non cancerous cyst(sebaceous cyst) it feels like a hard pimple with a tiny little scab on it. In addition she is full of Energy and acts normal. Just looking for a second opinion for a peace of mind .
