Some thoughts about dogs that vomit or regurgitate their food even hours after eating:
You may want to talk to your vet about this problem, since it might be important to differentiate whether or not the dog is actually vomiting, or is regurgitating.
1. Some dogs suffer from delayed gastric emptying. This can be a serious risk for later gastric dilatation and torsion, so if this condition is present, appropriate treatment should be instituted.
My standard poodle had a problem that sounds similar to the one you describe. As a 6 month old pup, I could feed her at 8 am, and if we went for a car ride at 3 pm, she would vomit up kibble that was whole and scarcely changed by digestion. This is not normal, food should move through the GI tract faster than that! I fed her twice daily because she would not eat more frequently (probably because there wasn't room in her stomach for more until much later than usual.)
It is possible to do some specialized diagnostic radiography with barium, but I felt that I wanted to simply try some treatment options myself first. (Since none of the things I tried would be harmful even if she did not have delayed gastric emptying.) I consulted my employer (a great vet) and my best friend (a veterinary criticalist) prior to treatment.
The first thing I did was to change her diet to an optimal protein, high carb, low fat diet.
Fat slows movement through the stomach, so you don't want to use it for an energy source. Protein levels should be enough to meet a growing dog's needs, but there is no reason to turn to protein as a major energy source. Protein that is not needed for growth and repair is simply deaminated and burned for fuel, the body cannot store it. Carbohydrates are a more ready form of energy and produce less waste material for removal by the kidneys. (There are several schools of thought on whether or not excess protein actually causes harm to kidneys, but at any rate, feeding excess protein is wasteful and expensive.)
Then we ground her kibble up and fed it as a liquidy slurry. This also speeds gastric transit time and increases digestibility. At this point, she had improved about 75%, and in order to increase the response, I eventually began giving her a medication to improve GI motility
30 minutes before each meal. She is also fed smaller meals but fed 3 times daily. This seems to have solved the problem. She hasn't vomited since we began this protocol, and it had made life much easier! Before, I could not easily take her in the car, or out in public. Now, at 19 months, she goes to class with me, makes therapy dog visits, goes shopping, whatever, with no embarrassing messes.
Because delayed gastric emptying is a risk factor for bloat and/or torsion, when she was spayed at 7 months, I had her stomach wall tacked into place to prevent torsion.
2. Another possible reason for frequent regurgitation/vomition is mega esophagus. This is a
much more serious problem, and can be congenital or acquired. It is truly life threatening, since the sufferer can aspirate gastric contents, which will cause a life threatening pneumonia. Again, your vet should be consulted. Radiography can show an enlarged esophagus, and then steps can be taken to minimize aspiration risk. Mega-e dogs should be fed in a totally upright position (sitting up in a special chair) and they should receive a low fat, easily digestible, slurry type diet for the same reasons listed above.
Just raising the food dish might help, but usually it is better to feed the dog in a more upright position.
3. Food sensitivities can cause dogs to vomit frequently, and you might need to try a hypoallergenic or sensitive stomach food. Again, consult with your vet for instruction in how to try to figure out what ingredient(s) is/are causing the problem. It takes time and care to use a process of elimination, but your vet can tell you what dietary items are more commonly implicated.
Final note: The Purdue University Veterinary School did a study for risk factors for GDV :dogsmile
gastric dilatation and volvulus) that found that feeding dogs from an elevated food bowl (in the absence of conditions that require elevation) was one of the top 5 risk associated with GDV. It is never recommended that you elevate the bowl (especially in dogs that are already prone to GDV, like shepherds (and standard poodles!!) unless there is a specific, known reason for doing so.
Good luck with your puppy. I strongly suggest that you discuss this with your vet at the next visit, before trying anything different, unless it would be to switch to a highly digestible, low fat food. (But it has to one that supports the growth of a GSD pup!)
And remember that sometimes pups simply outgrow the problem, given time.
I hope this info is of use.:dogsmile:
