Welcome to Justanswer! I am Dr. Altman and happy to assist you both today! So sorry to hear that your dog is having difficulties defecating. There are certain steps that can be taken to aid in this situation but if it goes >48 hours please consider a veterinary exam to assist him in defecating with medication +/- manual extraction1.) A high fiber food (more for longterm constipation issues if needed). This might include a light formula which will have a higher fiber content. This gives a dog a feeling of satiety and when the stomach
is full there is an increased urgency to defecate which will help empty the colon2.) Add water to the meals which is important in defecation and motility because it aids in lubrication3.) Regular walks. Leash walks are critical in emptying the colon completely. Especially an hour or so after meals. When the stomach is full the gi tract tends to start increased motility so there is a natural urge to defecate. Walking
15-20 minutes will help encourage that mobility and emptying of the colon4.) Supplements along with the light formula can include white rice (reducing the diet
to add this), 1 tbsp canned pumpkin twice daily, 1/2 tsp of miralax, carrots with dinner (I feed my dogs a full whole carrots with dinner)Unfortunately I do not advise over the counter enemas, these can be toxic
to dogs and should be avoided. If this continues despite these recommendations it would be best to see your veterinarian to ensure there is no issue with the anal glands, a motility disorder that might require medication to treat, or another metabolic cause of this issuePlease let me know if you have any additional questions. If you have more questions or if I can help in any other way, please do not hesitate to ask!
