Defaecation changes
If your pet has persistent diarrhoea or constipation lasting for longer than 48 hours, and there is any difference in the poo (like the presence of blood or mucus). You would better visit vet, and take a fresh poo sample when visiting if possible.Vomiting
Vomiting can be a sign of a developing allergy or a more serious infection. If your pet vomits just once or twice and nothing unusual about their behaviour or health, it would probably be no need to worry. However, if your pet keeps vomiting, you should go to the vet.Itching or flaking skin
The skin condition is a general indicator of your pets’ health. Healthy pets’ skin should be smooth and pink or black. If your pets’ skin appears persistent itching, sores, lumps and signs of dermatitis, a trip to the vet is a good idea.Urine changes
Changes in urine may involve the amounts or colour of urine, frequency or location. Your pet could have difficulty urinating that yelping or a hunched back when urinating.Appetite or drinking changes
The amount your pet eats and drinks could be an early indicator of some diseases, and these diseases are more common among senior pets. If your pet refuses to eat for a day or more or unusually excessive thirst, you should consult your vet.General lethargy, tiredness

Your pet might have: high body temperature, systemic disease (like low red blood cell count, liver or kidney disease), painful joints, spine neurological problems, senility changes.Coughing
Coughing is a non-specific symptom and may have multiple causes, like Kennel Cough(for dogs), upper respiratory tract infection/irritation, heart disease, heartworm disease, asthma, lung disease, etc. While it may not sound like a serious problem, sometimes it is a sign of some serious illness.Bad breathe
Bad breathe could be the result of dental disease. You might also find that your pets’ gum reddened or swollen. When severe, your pet may lose teeth, drop food from their mouths.Limping
