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
