Ruby is kinda constipated...remember she ripped up a peice of memory foam on Sunday, so I am a tad worried. She IS pooping but she seems to be straining a bit,and seems a bit dryer then what is normal for her. she is eating, she is playing, she is happy. She doesn't seem in pain, not sleeping any more, and right this second is currently running around teh house with my other dog ....So I am guessing its a minor bout of constipation....I know that pumkin will work but do I really want to give that to her at night? how long til it works? ( I don't want to be up with her all night long if I don't have to), do I really need to give her anything at this point maybe it will resolve over night on its own? How much would I give a 6lb dog without causing the runs, or the pain associated with stomach cramps?
