A good brand canned food is better than dry if it is constipation as they have much more water content in them. The pumpkin mentioned is good too. just try and get the pure pumpkin and not the pie mix w/ all the sugar and spices added.
Also Cod Liver Oil, either the liquid or capsules. Very good to get them going. And people too, lol....it's also great for the skin/hair etc...
Just keep watch and if he hasn't gone after those, then I would take him in as he could have a blockage of some sort.
Take care, Teresa ; )
I have to disagree with the vaseline because it's not water soluble. A better solution is a spoonful of canned pumpkin. The fiber should get things going gently.
How long has it been since your dog had a BM? Are there any other symptoms? If your dog is lethargic and the abdomen seems larger, you could be dealing with an emergency situation called bloat. Let us know what happens, and I hope it's just a simple case of constipation. :-)
vaseline. Put a glop of it on your finger and transfer it to the roof of the dog's mouth. Do it again in 12 hours, until you are satisfied he/she is running smoothly.
