Is Claritin safe for dogs with allergies? What should I know?

Yes, Claritin is among several over-the-counter antihistamine options that may be given for allergies. Frankly, they all offer only mediocre relief but can be helpful for very mild symptoms. I would still recommend touching base with your vet to make sure Claritin would be appropriate for Bruno with his medical history and any other medications he might be taking. If Bruno's allergies do not improve on an over-the-counter option like Claritin, there are much more effective options available by prescription from your vet. Hope this helps!

Loratidine (Claritin) can be given to dogs. Here is an information sheet that talks about dosing and side effects. ( https://www.petplace.com/article/drug-library/drug-library/library/loratadine-claritin-alavert-for-dogs-and-cats/ )

While a pill or two may not cause any harm other than increased drowsiness, if your dog got into a large or unknown amount it is best to seek veterinary care immediately or contact your local Animal Poison Control (if you are in the US you can call 888-426-4435 however there is a fee to use this service). They can provide treatment or let you know if the dose ingested is harmful. You may see signs like extreme drowsiness, or paradoxical reactions such as an increase in activity such as drooling, vomiting, etc. If you are seeing these signs, seek care immediately.

Oh no, Toffee! First of all, determine if Toffee ingested Claritin (loratadine alone) or Claritin-D (loratadine with pseudoephedrine). If she consumed Claritin-D, she should go to the vet immediately so that vomiting can be induced and so that she can be monitored, as this can cause significant heart rate elevations and neurologic signs. Also closely read the packaging material to assure that xylitol is not present in this particular tablet. It is used in some tablet forms of loratadine and is a bigger concern than the loratadine itself, as it is highly toxic to dogs (liver damage, low blood sugar, etc.). If you are unsure if xylitol is present, I recommend calling the company on the packaging or the ASPCA animal poison control center (888-426-4435). If xylitol is present, she will need to go the vet immediately to have vomiting induced and supportive therapy started. After ruling out ingestion of a pseudoephedrine-containg product and the absence of xylitol, there are likely no major concerns about ingesting 1 tablet of loratadine. There is a chance that Toffee may exhibit slightly excitable behavior, but if she seems overly agitated, you may need to take her to the vet for supportive medications. I hope that all goes well!

Singulair is not used for dogs, all other over the counter anti histamines you mentioned are usually non effective in dogs at all, Benadryl and Piriton are usually the only ones that sometimes work, but as a general rule anti histamines are not as effective in dogs as they are in humans unfortunately. for severe allergies most dogs will need a course of steroids which are prescription only.

Claritin, not Claritin D can be given safely to dogs. The typical dose is 0.5mg / kg of body weight. So for example, a 20 lb dog would get 4.5mg by mouth every 24 hours. I hope this helps! Please let me know if you have any other questions or concerns and I would be more than happy to help you further.

Unfortunately, by law it is illegal for the experts at Petco Pet Education Center, formerly Petcoach to give the dose information for any drug, including OTC drugs, without seeing the animal in person first. That's because doing so requires a veterinary client patient relationship which cannot be achieved via an internet forum. In addition, the experts cannot say for certain if a specific drug is safe for Rey. You will need to speak to her vet to see if it's safe to give her the Loratadine.
