Also - as an update, he pooped this afternoon. It was still loose and had a little blood in it. We will see what the vet says tomorrow. Again, he is acting totally normal. Fingers crossed.
How long has it been since the dog pooped?thanks for the response Tuxi, the vet rang back and she was not too concerned. He is still not pooping though so I have another apt for tomorrow just to make sure. He is still acting totally normal, we are walking a lot more than normal and one run a day. He is stoked about that. Eats great, excited to go out, just no pooping. I am thinking it is the white rice slowing him down. I would never normally feed it to him (or eat it) but that's what she recommended, white rice and lean meat. Maybe at least brown rice.
