My fiance showed up 3 days ago (Weds) with a boxer puppy (thought about 10 wks, vet says 7-8) who was rescued from a neglectful backyard breeding
situation. We took him to the vet the next day and they said he is dehydrated, quite underweight (he is very skinny, you can see every rib) and has a bit of a distended stomach, but otherwise in good health. He was given Rx wet food for us to mix with his dry to encourage his appetite.
Since then, he has been eating and drinking very well. He eats 2 big meals a day and 2 smaller. Right now we allow his dry food to be available at all times because he needs to gain weight (he needs to gain 3lbs and he is 6lbs).
My question is about him going potty. Obviously he is not trained yet but he doesn't seem to go very much at ALL. This is my first dog (I am a cat person) so my info is internet research. Everything I've read basically says he needs to go anytime he wakes up and anytime he eats or drinks. He doesn't seem to have any pattern to his potty needs.
For example, my fiance took him out at 1a last night and he went. I got up at 3a and took him out, he didn't go. I got up again at 5a and he didn't go. I gave him breakfast at 5:15 and he ate a large breakfast of wet food, dry food, and drank water. I took him out again and he didn't go. Now it is almost 7a and he still hasn't gone potty except a tiny tinkle (on the rug unfortunately). He played for about an hour (and I kept taking him out) and now he is napping in his bed.
Shouldn't he be going more? Is this maybe because he is underweight or something? Do I need to contact his vet or is this normal/okay sounding? He is in good spirits, loves to play and cuddle and doesn't seem in any way distressed.
My concern is two-fold - a) obviously his health, I want to know if this is normal and b) scheduling...if this was a work day, I'd be at my office right now and he still wouldn't have gone potty.
