Let us know what they say.

I know that bloating is a common symptom of kidney disease. It isn't always noticed mind. I only noticed our old Monty losing weight and mention it to my dad who just said: "Well, he's eating". Me dad being me dad didn't do anything about the weight loss and then three months later, Monty took a bad turn, vomitting and all the rest, went to the vets and didn't come home. If caught early enough, Kidney disease can be treated but me dad was always a sod for leaving them and hoping things would just go away because he didn't want to take them to the vets and "Waste", money.

Having an old dog myself, I know how horrid all this stuff is. I hate it when you notice these things and start fearing the worst. I hope things go ok at the vets.
