Urinating
All pets (especially dogs) want to live in a clean environment, just like humans, so when your dog begins to urinate in your home, something is wrong. If everything is fine, there is no reason for a dog to purposefully empty its bladder.
It is possible that your dog is urinating in the house because of a problem with his kidney function; however, it is also possible that he is suffering from another medical condition that needs to be investigated.
Closing or Opening Mouth Slightly
The mouth of a dog is typically open, calm, and relaxed. This indicates that the dog is content and content. But what if your dog’s mouth is only slightly open, his face is tense, and he appears to be uneasy?
If you keep an eye on your dog and notice that its mouth is slightly open (or slightly closed), it is likely that the dog is stressed, frightened, or suffering from pain.
