Hello Ron, I'm Dr. Deb.

I recently came online and see that your question about Alfie hasn't been answered. I'm so sorry that you've had to wait for a response,but if you still need assistance, I'd like to help if I can.

As you might expect, there could be several different reasons why Alfie can't defecate ranging from constipation issues (secondary to getting older and losing muscle tone) to masses compressing the colon or problems with the nerves which come from the spine, to cite a few examples.

If a thorough physical exam has been done and no underlying anatomical problems appear to be the issue, then there are a number of treatment options if constipation is the problem:

1. Hairball laxatives such as Laxatone or Laxaire which are for cats but work well on smaller dogs. I typically suggest 1-2 inches 2 times a day.

2. Canned pumpkin (NOT the pie mix); 1-4 tsp daily in food for small dogs. Squash can be substituted for pumpkin. The amount can be increased until softer stools are produced.

3. Over the counter, human Miralax 1/4-1/2th tsp twice daily

4. Raw bran flakes (wheat bran, not the cereal) at a dose of ¼-1/2 tsp daily

5. Docusate Sodium (Colace) 25 mg once or twice a day for small dogs although I wouldn't use this product every day if the problem becomes persistent.

6.Single pediatric glycerin suppositories can be given if the patient is really constipated. You'll just want to read the label to ensure you purchase those which only contain glycerin.


There are other options such as lactulose, Cisapride or even higher fiber prescription diets but these options would need to be discussed with your vet and prescribed by them.

I hope this helps although, again, my apologies for the delayed reply. Deb
