You’ll notice that your dog skips its meals and turns down food, even if it’s something you know it’ll eat. This is one of the most obvious signs of illness.
It’s a little difficult to know if a dog has fever or not. When the dog has high body temperature, try to place your finger near the openings of their ears or rub their stomach area. If you think that the dog is warmer than usual, you should consult your vet. Many different illnesses can cause fever, so always have your vet’s number in handy in case you need to contact him or her.
Diarrhea or Vomiting
Diarrhea or vomiting can be caused by an illness or something that your pet ate that caused it to have an upset stomach. Food-induced diarrhea or vomiting can be easily cured with home remedies, but if it continues to happen for a few days, or if you notice blood on their stool or vomit, then it’s something more than just bad food.
Like babies and small children, dogs can sometimes swallow small household objects that can irritate their digestive tract. Diarrhea or vomiting can also be a sign of parasitic infection. Other changes like constipation, infrequent or frequent urination and unusual stool texture needs to be checked immediately.
Physical appearance and movement
If you notice their fur thinning, patching off, or becoming dull, this could be a caused by illness. Feel for any strange bumps or growth under their skin, discharge or mucus coming for their ears, nose or eyes, and the color of their gums. If they start having problems walking, sitting, running or even standing up and keeping balance, this could be a sign of DM in dogs, arthritis or some other joint, nerve and muscle problems.
