I will read that article, thank you.
I found a vet in Canada that does surgery. However he wouldn't give any advice over the internet. He is too far from me so that plan is out. I contacted an internet vet in the US and she said it sounded like cloacalith. With that reassurance, I started a treatment plan.
I soak her twice a day, she gets coconut oil to slide things down and out easier, and greek yogurt in case she needs the bacteria. She soaks in warm water for a long time, probably 45-60 minutes. She is fine with this. While she soaks lots of gunk gets loose and comes off in the water so I can see it better when she is out of the water. I blow warm air on her while I scrape whatever I can get off. Things come off in crumbs. The black tissue is actually pretty tough to deal with because it rips the skin off and therefore it bleeds. A little pressure stops it. When I get a bleeding spot, I stop on that spot and move around trying to not hurt her. I keep going as long as she lets me, and she does, and as long as I can get anything come off. The goal is to get the necrotic tissue off so the normal tissue can stretch as it is supposed to.
During the day she was in the dog crate. I could hear her complaining every time she was trying to poop and probably every half hour. It must be painful. Now this evening after I got some black stuff off, she was able to poop with much less whining. The poop is runny because I gave her coconut oil and she gobbled it. I don't know where I read to give a drop of oil. I gave a spoonful and she loved it. Same with the greek yogurt.
It is possible I am dealing with multiple problems. Fly strike that damaged the skin and caused necrosis and scarring, which is why the tissue can't stretch, and caused an impaction. She might be trying to get rid of an egg, which I can't feel when she is not straining, but I can see it when she is straining. She is in the stance of laying the egg, and the channel comes way down, the size and shape is equal to an egg inside which can't come out as long as the cloaca is full and the skin is a hard shield around the exit. Is it possible it is just the rock the size of an egg? yes it is possible. An egg inside is also a possibility. Only and x-ray could tell for sure. She is about 2-3 years old, closer to 3. She could be still laying eggs.
This whole soaking, picking and drying takes 2 hours each time. She doesn't try to escape, she is enjoying it and like she knows I am trying to fix whatever is bothering her, she stands there and lets me do it.
If she were fighting or crying or squirming, I would give up. She is not lethargic, she is eating drinking, scratching and socializing and running. I hope this works and I will keep going at it as long as I can see that it helps. If it looks like I am making things worse, I will stop and euthanize her. For now I can't see that there is pus and a new infection. I put polysporin with pain medication in it, and hopefully it will help soften whatever is so tough and dry there.
