Meet Oreo. She is a stray dog who I meet everyday when I go to work and come back from work. Yesterday I saw her hind legs coated with blood and took her to an emergency veterinary hospital. She had an extremely laceration in her left hind leg. She got some sutures. I brought her home and am currently looking after her till she is ready to leave. I will try to also find someone to adopt her, but frankly chances are slim. 

Please note, I'm not in the US, I'm in a country where street dogs are reviled and people prefer to buy breed dogs but not adopt Indian pariah dogs who typically roam on the streets. I already have a dog and my current lifestage makes it difficult for me to keep her. 

Now on to the question

She is currently unable to move much, just crawls around in the room. I picked her up and took her to the balcony to make her pee, she didn't do it willing but when I pressed her tummy a bit she involuntarily peed. When I picked her up again, she involuntarily peed again. I feel terrible and horrible that she has been holding in all this pee for hours and hours. I am now going to take her to pee every few hours. 

On to the poo problem. She cannot stand up. She refuses to eat, she has only had a handful of kibble and half a boiled egg since the morning. She hasn't pooed even once but I have definitely smelled some farts. I don't know how to make her poo. 

Any suggestions, directions will be welcome.
