Is it safe to give my dog human hydroxyzine for separation anxiety?
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.

What human antihistamine is safe for my dog with allergies and liver issues?
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.

My puppy ate liquid hydroxyzine and has diarrhea. Is it serious?
Thanks for using Petco Pet Education Center, formerly Petcoach. The hydroxizine itself doesn't usually cause diarrhea (we use it in dogs too). However, I worry that there could be an inactive ingredient causing Bayley trouble (artificial sweetener? alcohol? flavoring?). If the diarrhea is still profuse or if you see any other signs, call the Pet Poison Helpline and head toward the nearest emergency vet. The Pet Poison experts will also consult with your veterinarian on the recommended treatment throughout the case. Be sure to have your daughter's bottle of medication with you to give them all the ingredients, strength, etc. Pet Poison Helpline 855-764-7661 Best of luck to you and Bayley.

What are Benadryl alternatives and where to buy dog supplements?
You should have Diphenhydramine, that is the same as Benadryl, just not the brand name. That is the active ingredient in Benadryl. You should have an equivalent to this where you are. Check drug stores and ask someone and I am sure you will be able to find an alternative. As for the fish oils, you should be able to perform a simple online search for canine fish oils or visit any local pet store near you that offers pet supplements.
