How To Choose The Best Antihistamine For Dogs With Skin Allergies?
When it comes to choosing the best antihistamine for dogs, the most important point is always the ingredients. An ideal medication for dogs should not be formulated with toxic substances to dogs.
Here are some of the key points you should look at in your dog’s allergy medication:
Formulated For Dogs:
Antihistamines or antihistamine supplements formulated for dogs are always recommended to use. Over-the-counter antihistamines can be used to treat dog skin allergies, but they will not be as helpful to soothe the redness and irritation.
Some over-the-counter antihistamines formulated for the human body can be toxic to dogs. Well-known over-the-counter antihistamines like Benadryl are available in various formulas. But all formulas are not safe for your dog either.
Antihistamine poisoning or overdose can occur by using medication that is not formulated for dogs but humans.
Free Of Toxic Substances:
As we have previously stated, many over-the-counter antihistamines are formulated with substances that can be harmful to dogs. If you are planning on treating your dog’s skin allergies with common allergy medication like Benadryl or Zyrtec, then reach out to a veterinarian first.
Antihistamines like Benadryl are available in many formulas. You should not administer antihistamines with decongestants to your dog.
If you are unsure whether your antihistamine has decongestants or not, check out the label. If the name of the medication is accompanied by a “-D”, then it has decongestants.
Antioxidants:
Omega-3 fatty acids, antioxidants, etc., can help soothe the rashes and inflammation in your dogs’ skin within an hour of taking the medication.
If your dog has been suffering from an allergy for a long time, then feeding him allergy immune supplements with antioxidants and omega 3 will boost the recovery.
The fatty acids of Omega 3 will soothe the dry and red skin. Antioxidants will soothe the itchiness. Along with this, antioxidants and probiotics in the supplements will boost your dog’s immune system.
Made With Natural Ingredients:
If you are feeding your dog allergy immune supplements, then be sure to opt for a supplement made with natural ingredients.
Many supplements use artificial flavors, synthetic colors, and preservatives to enhance the supplements, leading to more health complications for your dog.
Frequently Asked Questions:
Q1. Why dog’s body produces histamine?
Any foreign particles like pollen, dust, dandruff, etc., when coming in touch with mucus membranes of your dog’s mouth, nose, lungs, throat, stomach, and intestines, activate the release of histamines.
If your dog is suffering from allergies, histamine can quickly be released from red blood cells into the bloodstream as allergies lower the body’s immunity. Thus allergic dog produces more histamine, resulting in itching over the body.
Q2. What does histamine do?
Histamine is a type of chemical produced from red blood cells that stimulate nerve for itching.
How do antihistamine chews cure itching?
Most antihistamine chews contain nutrients rich natural ingredients which contain Omega-3 fatty acids, EPA, DHA, etc. These essential nutrients improve the body’s immune system and control histamine production. It also improves skin health and skin coat. Thus cures itching in the dogs.
Conclusion:
These medications were our top picks for the best antihistamine for dogs with skin allergies.
As we have previously mentioned, administering antihistamine to your dogs without consulting a veterinarian is not recommended by us.
Antihistamine overdose can lead to terrible aftereffects. If you would like to keep your dog on allergy immune supplements, consulting a veterinarian before is recommended. Allergy immune supplements can treat long-term allergies without harming the dog’s health in other ways.
