Good Morning and welcome! I am Dr. Loretta, a licensed veterinarian and I am happy to answer your question.
This behavior is not normal and most often means that your gal has a mild digestive disturbance. The treatment for this is as follows:
Fast her for 12-24 hrs to allow the digestive tract to calm down and heal.Give her Pepcid AC or Famotidine at 0.5 mg per pound every 8 hrs. That can be purchased over the counter at the pharmacy.Give only small amounts of water during the fast or ice cubes After the fast, feed rice and boiled chicken (2/1)
If the behavior has resolved, then wean her back onto regular food. If the it persists especially during the fast, take your gal to your vet for an exam and lab work to determine the cause for this. It may only be an odd behavior that your gal has developed.
Does that make sense to you?
Please let me know if you have ANY other questions. My goal is to give you 100% satisfaction and if you are not yet satisfied, please REPLY so I can clarify for you.Sincerely, ***** *****
Your gal sounds like a sweet girl....i am glad she is protective and I am happy that she is doing well.Good for you!!
