Thank you for using Petco Pet Education Center, formerly Petcoach! While hydroxyzine is an antihistamine commonly used for allergies and might cause mild sedation in dogs, it is unlikely to resolve Hunter’s separation anxiety. I recommend trying positive reinforcement, providing distractions, or even using calming supplements for dogs or a product known as a “thundershirt” prior to resorting to medications. You should consult with your vet regarding any medications you may want to give to Hunter to confirm that there will be no interactions with anything he is currently taking and that the dose is appropriate for his size.

Hydroxyzine and Diphenhydramine are both human anti-histamines commonly utilized in the vet field for allergies. Histamines do not directly affect the liver, but will certainly have indirect effects.

It sounds like you may need a prescription strength medicine to help your dog become more comfortable. Your vet will need to examine your dog to ensure they are otherwise healthy (and to start a valid client/ patient/ vet relationship to legally dispense medicine) and then will decide which medicine would work best. There are newer products such as Apoquel and Cytopoint which may be appropriate. Your vet may also suggest an eye ointment to apply. You are welcome to request a consultation with one of the Petco Pet Education Center, formerly Petcoach veterinarians to prepare for your vet visit.

Hydroxyzine is not FDA approved for use in veterinary medicine, but it is frequently used "off label" to treat allergies and itching in cats and dogs. Legally, we are prohibited from recommending prescription medications in the absence of a physical exam and a VPCR (veterinarian-patient-client relationship). What you can do, is contact your vet for a dose based on Boba's body weight. Just as in people, antihistamines will affect pets in different ways. You may find it works well, just ok or not at all. Check Boba over for fleas, which are the most common cause of itching and scratching. If found, treat him topically or orally for at least 3 consecutive months but preferably year round. You will also need to treat the environment for fleas. This means vacuuming everywhere and washing all bedding. This should be followed up with a cat safe area treatment to prevent re-infestation. If there are no fleas, you will need to have Boba examined by your veterinarian to diagnose infection (bacterial or fungal), other parasites (mites) or other allergens (food, environmental, inhaled, contact). It can be very frustrating given all the potential causes for allergic reactions. Discuss allergy testing, food elimination trials and hydrolyzed diets with your vet.

Hello. Honestly, I recommend either Nordic Naturals or Bayer Free Form Snip Tips. Both of these are highly recommended by veterinary dermatologists, too. You will need to call other veterinarians to see who carries Cytopoint. It is an excellent product & most of my clients love the convenience of only needing a simple injection once ever 6-8 weeks to control their pet's allergies. Thanks for using Petco Pet Education Center, formerly Petcoach.
