External parasites and internal parasites in dogs can vary in symptomology, depending on the parasite. For example, the symptoms of a sick dog by ticks compared to those due internal parasites will differ.

Very general parasites on dogs symptoms include:

Fleas in dogs can also transmit various diseases, parasites such as tapeworms or even cause anemia. The most characteristic disorder of fleas is allergic dermatitis in dogs due to flea bite. Dogs that are sensitive to flea saliva will present a dermatological reaction characterized by alopecia and lesions, especially in the lumbosacral area.

Following your dog’s vaccination and deworming schedule strictly is key in preventing parasites in dogs[3].

Sick dog symptoms shaking: cognitive dysfunction

Older dogs are prone to suffering from cognitive dysfunction syndrome, similar to Alzheimer’s in humans. Cognitive dysfunction syndrome in dogs symptoms can go unnoticed if blame is placed on old age. Dogs suffering from cognitive dysfunction syndrome may:

  • Sleep a lot, especially during the day.
  • Shake.
  • Appear restless.
  • Cry and moan a lot.
  • Urinate or defecate inside the home.
  • Isolate themselves.
  • Become unresponsive to stimuli.
  • Present compulsive behavior.

In order to diagnose this syndrome, a veterinarian must rule out any possible physical causes. For example, as we’ve already mentioned, kidney disorders in dogs usually cause increased urination. Therefore, urinating inside the home can be linked to several different causes. This is predominantly why we place so much emphasis on visiting a veterinarian if any of the above symptoms are noticed.
