My dog has been pooping thin and gets pain when jumping off the bed.
Thin stools can sometimes indicate gastrointestinal issues, such as inflammation or a partial obstruction. Additionally, pain when jumping off the bed could be related to joint or muscle problems, which are not uncommon in older dogs.
First, inspect Chico's painful area. Check his joints and bones(especially the patellar) If Chico's joints are swollen and hot, it can be a ligament injury or a fracture. In this case, you should visit a nearby vet for an accurate diagnosis and treatment.
If there is no abnormality in the range of joint movement of him, and there is no doubt of a fracture, it may be a simple sprain.
For the thin stools, make sure Chico stays well-hydrated by providing plenty of fresh water. You could try feeding a bland diet for a few days, such as boiled chicken and rice, to see if this helps normalize the stools.
Regarding the pain when jumping off the bed:
Try to limit activities that require jumping or high-impact movements. And providing a ramp or steps can help Chico get on and off the bed more easily.
If these symptoms persist or worsen, it would be wise to take him to a vet. They can perform a thorough examination and possibly recommend diagnostic tests to determine the underlying cause of these issues.
If you have any further questions, please feel free to ask. Thank you.
