my dog

My dog was bleeding today and he still might be bleeding but i doubt it. So me and my friend were chasing eachothers dogs around and we went back t his house because his house was flooding, my dog was eating my friends cat food and thats when isaw the blood and where it was comeing from. it coming from him paw. Either his indentations in the paws between his fingers got ripped a little ( but i doubt thats the reason), or his nail was bleeding because he was digging earlier. So thayts what happened with my dog. My D O double G.
