Your dog might be ill if he starts to retreat to his crate, dog bed, or another room when he normally would lie near his family.
SIGN 1
Symptoms include coughing, loud breathing, gagging, and nasal discharge. You have to see a vet immediately if the gums and tongue of your dog are more blue-ish whereas they should be pink.
Breathing Issues
If the poop of your dog doesn’t contain any solid texture and is watery then your dog is suffering from diarrhea. Diarrhea should be checked with your vet.
No appetite
If your dog is constantly scratching himself, has diarrhea, dry skin and runny eyes then you could have an autoimmune reaction or other health issues.
