Dog Allergies & Scratching

Dog allergies associated with scratching are topical allergy reactions from irritants in the environment such as weeds, grass and chemicals. If your dog has a weak immune system, he may be prone to developing allergies on his skin. Constant scratching leaves your dog vulnerable to infection because sometimes the skin breaks, resulting in an open wound. You will know your dog has a skin allergy if he has no fleas and still scratches often or if he has lesions or patches of hair falling off his skin from hives.

  1. Identification

    • An allergy that causes scratching is a false immune reaction to something in the environment that is not harmful to your dog. Symptoms such as hives and excessive scratching are what harms your dog. The body reacts by breaking out in hives or causing itching from a perceived threat.

    Prevention/Solution

    • Treat him for ticks and fleas first. If he still scratches, talk to your veterinarian about other options. Remember that a modest amount of scratching is normal for every dog. You only need to worry if your dog is scratching so often that he is breaking the skin.

    Effects

    • Scratching from allergies has the potential to cause serious skin infections in dogs. The Doctors Foster and Smith website states that too much scratching causes hair loss as well, indicating a possible underlying medical condition. Bacteria can enter the skin from an open lesion. Keeping your dog clean and relieving the itch is vital for the health of his coat and skin.

    Time Frame

    • The time frame for topical allergies varies for each dog. Some dogs may only develop this type of allergy when exposed to chemicals or during the spring and summer months. The allergies can last for one day to several weeks.

    Considerations

    • There are many things you can consider if your dog is suffering from topical allergies. Attempt to remove the irritant. For instance, if you know a certain plant causes your dog to break out in hives, remove this plant from your backyard. You can also ask your veterinarian about allergy medications. Keep your dog's skin and coat moisturized with coconut or olive oil. The additional moisture will soothe her skin from irritation caused by scratching.
