Based on your description, Wade may have a condition called colitis. This is an inflammation in the large intestine most often caused by a change in diet, eating something they are not used to or a stressful event. It can be secondary to many other things. It often results in diarrhea/loose stools and straining to defecate. If he's acting normal otherwise, you can start by withholding food for 12-24 hours, then introducing a bland diet of plain boiled chicken and white rice. You can also add some canned pumpkin puree as the fiber can help to firm up the stools. As long as the stools normalize, you can then start mixing in his regular dog food. If the diarrhea continues despite these things, I would recommend taking him to a veterinarian for an exam. They will most likely recommend a fecal exam to look for parasites and sometimes when colitis doesn't resolve on it's own, they are treated with an antibiotic.
