Hello all, sorry for the long post...
I posted a few weeks ago that I thought my new whites looked a little bloated. He was acting normal (such as soaking, eating, and being active). I came to the conclusion (through my observations and comments by others) that maybe he was just a little on the porky side. However I have noticed some odd behavior recently. He still has a great appetite, is fairly active (not nearly as active as my other whites though) and his stool looks solid. However I notice that he doesn't soak. He sits by the edge of the bowl staring at the water but wont go in. If he's placed in it he immediately climbs out. He looks like he's soaking though because he's puffed up. This has me thinking that he's retaining water due to a kidney malfunction. Its like he wants to soak, but he's already "filled to capacity" sort of speak. Another thing i notice is that he takes about 3 breathes, each time puffing himself up more and more, then exhales and deflates himself. My other whites does not do this. For you experts out there...do I have a concern?
ps, another point now that I think about it, when I picked him out at petco, he was noticably smaller than the other whites he was in with (I picked him for his color). I'm guessing they all have to be from the same brood. Could he have been born with a kidney problem, and thus his "failure to thrive" is evidence of that?
