#2- Consistency- Depending on the dog breed, and size a dog’s feces should be similar to a human’s. It has shape and is firm, but compressible. Abnormal would be called a really hard or dry stool, but also a watery one.
#3- Frequency- If you are feeding your dog as much as you are supposed too, then you should know that your dog should defecate once or twice per day. If your dog defecates more than that, then you should take your dog to the vet for a check.
#4- Odor- We all know that a dog’s poop smells, but please pay attention if you think that your dog’s poop smells really bad. If so, then you should take your dog for a vet visit. Digestive disorders can cause a foul odor or excessive gas and your veterinarian can help.
