There are many possible reasons. Firstly, make sure any change in your life pattern is not affecting the dog. It could be the dog's way of grabbing attention, if the dog is not happy with something, he/she wants you to take notice.
Another reason could be the dog's dietary needs have changed, either you are feeding the dog too much or too little protein. Try rotating your dog's food.
I am assuming your dog has no other health related issues.
PLEASE take that puppy to the vet. In puppies, blood in the stools and fever are signs of Parvo virus. Untreated Parvo virus can be fatal to a 9-week old puppy.
TALK TO YOUR VET IMMEDIATLY
she could be pregnant
Yes you should
How long before you worry about old dog not pooping ?
what!
The master is pooping
It sounds like your dog is very ill, please go to the vet NOW this is an emergency!
because....it wants to? You need to train the dog to not do that.
dont feed it corn
No it's not true. However, putting its nose close to it and saying no and giving it a tap on the but does help!
Your dog may be pooping more and sleeping more than usual because it is getting sick. Your dog may also just be getting old.
Pick it up
It could happen, she is fat and uncomfortable and does not want to be bothered.
