On Casey's referral, we took Q-tip to the Mt Pleasant Animal Hospital for her ultrasound scan. Yes, the kind pregnant women undergo to look at their unborn babies. Q-tip hates to be on her back, but we had to hold her in place anyway while the tech applied the gel and manipulated the scope around her (newly shaved) belly area.
The pictures from the scan were quite incomprehensible to us, so the tech pointed out the "masses" in the liver and the sedimentation in the kidneys, not uncommon in older dogs. However, the nature of the masses was still unclear. Only a biopsy could tell us for sure if they were benign or... otherwise.
Scan results have gone to Casey. Let's see what he can tell us.
