Hi and thanks for posting on Petco Pet Education Center, formerly Petcoach. This is very concerning and may be due to something more serious than just simple constipation. Abdominal fluid due to liver disease, heart failure, kidney failure, or cancers can be a cause as well as endocrine disease such as Cushing's disease or parasitic infections such as a heavy roundworm infection can be potential causes. I recommend Garlic see her veterinarian as soon as possible. Your vet will do a hands on exam and may recommend x-rays to check for free fluid in the abdomen and may run blood work as well to help pinpoint a cause.
