I am so sorry I am just seeing this now. CCD is friggin' horrible, and I am 99.9% sure it came with Pixel's kidney's failing too. Pixel was never the brightest so sometimes it was hard to tell if he was struggling or just Pixeling....
You know I am always here for the bad days. And the good days.
Old dogs are not for the faint of heart. Everyday is an evaluation and trying to do what is right by them.
Sending you and PiperMan lots and lots of love.
