Thanks for the answers to my questions.
If Annie is constipated, then this might explain her discomfort when you touch around her hip or stomach area.
When it comes to constipation issues, there are actually several options for you to try at home: manual removal and/or oral laxatives. If she's not badly constipated, then you may be able to provide her relief without a vet visit.
1. Sometimes if you can remove enough hard feces that are present right at the anal opening, the dog is able to evacuate the remainder. I frequently suggest this method for many owners who have dogs with this problem but since she's so small, I'm not sure if you'll be able to do it.
But, if you'd like to try, the following is how you would do so: Place a latex glove on your hand and lubricate it really well with K/Y jelly or Petroleum Jelly and lubricate her rectum, too. Gently insert your index finger into her anus up to your first or second knuckle, and hook your finger into fecal material and gently retract it. You may need to perform this procedure several times.
I would have someone helping you since this may be a little uncomfortable for Annie and you don't want to get injured yourself.
Iunderstand that this is not something that everyone will feel comfortable doing.
2. If you have a large syringe or turkey baster, you can also give her a warm water enema which is probably what will work best for her. Obviously, this is not for the faint hearted, though. I would lubricate the end of the syringe or baster as I mentioned above, gently insert into her rectum about 1 inch and gently squeeze the warm water into her.
You may also need to repeat this procedure several times to loosen up the hard stool.
Every step should be done gently so as not to cause harm.
3. You can give her an over the counter, enema such as a single pediatric glycerin suppository. Just read the label to insure that it only contains glycerin.
Oral laxative options (which may be effective if she's not badly constipated and to prevent recurrent episodes):
1. Laxatone or Laxaire (or similar products) which are hairball laxatives for cats. These products will work very well on a smaller dog like this. They are available at pet or grain stores. You would give 1-3 inches 2-3 times a day.
2. Canned pumpkin (NOT the pie mix); ½ -1 tsp daily in food
3. Over the counter, human Miralax 1/4-1/2th tsp twice daily can work very well.
4. Oral Docusate Sodium (Colace) 25 mg once or twice a day for small dogs.
Encourage fluid intake by offering her canned or wet food or low sodium chicken or beef broth.
I suppose it's possible that something else is going on such as she may be experiencing discomfort from gas. If that's the issue, then you can safely give her human products for this problem such as Gas-X or Phazyme or Little Tummy's ...anything with Simethicone on the label. The dosage amount is somewhat empiric but I typically suggest about 1/4th of what a human would take.
I hope this helps to provide options for you to consider. Deb
