Why dogs scratch - part 2
A: Last month, we talked about the general causes of itching, such as having an ear infection or an allergy. This month, we will talk more specifically about itching caused by allergies.
Both inhalant allergies and food sensitivities primarily manifest themselves with itchy skin. Other symptoms include anal itching, shaking of the head, ear inflammations, licking front paws, rubbing faces on carpeting and rarely vomiting, diarrhea, flatulence, sneezing, asthma like symptoms, behavioral changes or seizures. Many people don’t suspect food allergies as the cause of their dog’s itching because their pet has been fed the same food all its life and has just recently started having symptoms. However, animals can develop allergies to a substance over time, so this fact does not rule out food allergies. Another common misconception is that dogs are only sensitive to poor quality food. If the dog is allergic to an ingredient it doesn’t matter whether it is in premium food or the most inexpensive brand on the market. One advantage to premium foods is that some avoid common fillers that are often implicated in allergic reactions.
Dogs are not allergic to a dog food per se; rather they react to one or more of the ingredients in the food. Some of the most common culprits are beef, pork, chicken, milk, whey, eggs, fish, corn, soy, wheat and preservatives. Many animals are now developing allergies to lamb as well. This was once thought to be very hypo-allergenic, but the more it is used, the more sensitivities are springing up.
There are many hypoallergenic diets available and they must be fed for up to 10 weeks to see if they will help with the allergic symptoms.
Fleas are another common cause of allergies. The severe itching and resultant hair loss is caused by a reaction to the protein in the flea saliva. A single bite can cause a reaction for five to seven days. Good flea control is accomplished by either a pill or a topical that is recommended by your veterinarian.
Next month, we will discuss the treatment options available for your pets.
