Okay- I will give this a shot for you to ask your vet about. Dogs that have inflamed colons or low levels of pancreatic problems, can easily need to go poop in stress. Strange as this may seem- if there was one of these two underlying conditions for a while, and something happened, maybe now she sees the crate as a stress.. Two different events- meeting at one time.
Femka has this condition- stress will make her have to go. The vet suggested her thyroid maybe be a contributing factor- and after watching her, I had her tested. Sure enough it was. Now - you are thinking-- WHAT ON EARTH DOES THE THYROID HAVE TO DO with the colon or bowel. Actually the thyroid is the regulator for so many other functions.. Even helps her manage pancreatic fluids. Femka has a spot on her spleen- the enzymes this creates she would not be able to handle without the thyroid medication, creating stress diareah as well.
Occasionally- when I leave Femka to go out- she will poop in a matter of minutes after I have left.I have found a coalation between her not having her morning pill early enough before I leave, and this event.. Now- if I am going to leave- I make sure if nothing else, she gets her pill 3 hours before I leave. And its not seperation anxiety either as we taped her on a camera to see if there was any evidence of this. It does make her a little nervous and without the thyroid pill, just enough to create the sensation she has to go..
Have your doctor do a full thyroid panel. Meaning like here, it goes to Michigan state. If low but in range but barely, thyroid medication will help alot in regulating the pancreatic fluids, and colon enzymes.
Short term solve would be for her to sleep in your room, out of her crate. Put up a child gate so she doesnt have to worry about the whole house. To start with- take a " nap" nap today. Get a comforter put it on the floor so she knows thats "her" spot-.. Even if you just lay in bed and read- this will give her the idea before tonight.
Other indicators of thryoid- dry coat- , weight, "worry" , seeking cold, or getting too hot easily. ( hypo or hyperthyroid.) . Talk it over with your vet. This could be behavioral as in this is triggering worry in the crate- especially if now she has done this enough and knows she shouldnt, triggering worry- to excess colon enzymes or pancreatic enzymes- then the behavior turns to a down spiral verses a up sprial- all because of a medical problem.
Thyroid problems can also trigger behavior problems as the brain is " mis firing" meaning more worried than they would have been, more fear than they would have had.. I have posted so much on how femka was when we got it- and most ended up being a medical reason triggered by hyperthyroidism. I never really realized prior to femka just how MUCH the thyroid function controls/ contributes into the other organs.
