When accidentally ingested by dogs and cats, antihistamine poisoning can result in clinical signs of severe agitation, lethargy, sedation, aggression, abnormal heart rate, abnormal blood pressure, vomiting, diarrhea, inappetance, seizures, respiratory depression, and even death.
Your vet will give you more specific instructions for your dog, but the general recommended dosage is 0.2 milligram of Claritin for each pound of your dog`s weight. According to this general outline, if your dog weighs: Between 1 and 14 pounds: Give a maximum of 2.5 milligrams of Claritin twice daily.
Claritin® can be used but is not typically recommended by veterinarians as some forms of Claritin® contain decongestants such as pseudoephedrine which is very toxic to dogs.
Vets generally prescribe Claritin for dogs in a dosage 0.2 milligrams per pound of body weight. This can translate as giving a small dog around 5 milligrams of Claritin every day, or 10 milligrams for a larger dog.
Claritin dosage for dogs

The regular dosage of Claritin (loratadine) for dogs is 0.2 mg for each pound your dog weighs. Typically vets will recommend 5 mg every 24 hours for small to mid-size dogs, and 10 mg a day for larger dogs such as Labradors.

Loratadine (Claritin): ¼ mg per pound (half of a 10mg tablet per 20 lbs) once daily. Clemastine (Tavist-1, Antihist-1): 0.02mg per pound (one 1.34mg tablet per 65lb dog) twice daily.
Recommended Claritin Dosage For Dogs

The recommended dose for Claritin is 0.2 milligrams per pound of body weight every 12-24 hours. This is only a general recommendation, and as with all medication, you should consult with your veterinarian and have them give you the appropriate dose for your individual dog.

Benadryl is safe to give your dog for allergies, anxiety, motion sickness, and vaccine side effects. Though a typical Benadryl pill is 25 mg, you should only give your dog 0.9-1.8 mg per pound of weight. Make sure that the Benadryl you`re giving your dog only contains diphenhydramine.
Do not give your dog Claritin-D because it contains pseudoephedrine, which is highly toxic to dogs.
Each tablet or capsule of Claritin contains 10 mg of loratadine. The adult Claritin 24 Hour dosage is 10 mg (1 pill) by mouth once a day. Don`t take more than 1 pill in a 24-hour period. If swallowing pills is tough, there are chewable tablets for adults that have the same directions, as well as ODTs.
A small dog will need much less than a big dog to receive the same positive effects. According to the Merck Veterinary Manual, the safe dosage is 2-4 milligrams of medication per kilogram of weight, or 0.9 to 1.8 milligrams per pound.
Official answer. Yes, you can give loratadine to dogs, it is usually well tolerated and is unlikely to produce side effects such as drowsiness that tend to happen with some of the older antihistamines, such as diphenhydramine (also known as Benadryl).
The dosing schedule is also much more convenient, with dogs weighing over 10 lbs getting a single 10mg tablet once daily. Dogs weighing less than 10 lbs can have half of a 10mg tablet once daily. Chlortrimeton is another excellent antihistamine for dogs, and is the drug of choice for kitty allergies as well.
Can you give dogs human antihistamines? Antihistamines with the active ingredients of diphenhydramine, chlorpheniramine, cetirizine, clemastine or loratadine are usually safe for most healthy adult dogs.
Claritin tends to start working within 1 to 3 hours after taking it. The difference in time can depend on which type of product you take. Oral tablets seem to kick in faster than capsules. Claritin`s full effects should be felt about 8 to 12 hours after a dose.
Claritin blocks the action of histamine, a substance in the body that initiates allergic symptoms like itching, sneezing, runny nose, and allergic skin rashes. A difference is that Claritin D contains a decongestant and is also used to treat nasal congestion and sinus pressure.
Over-The-Counter Antihistamines

The human antihistamine Claritin (loratadine) is generally safe for dogs and can provide allergy relief.

The Merck Veterinary Manual recommends administering 2-4 milligrams of Benadryl per kilogram of body weight, two to three times a day.
Adults and children 6 years and older: The typical dose is 10 mg by mouth once per day. The maximum dose is 10 mg per day. Children 2 to under 6 years of age: The typical dose is 5 mg by mouth once per day. The maximum dose is 5 mg per day.
CLARITIN Tablets contain 10 mg micronized loratadine, an antihistamine, to be administered orally. It also contains the following inactive ingredients: corn starch, lactose, and magnesium stearate. CLARITIN Syrup contains 1 mg/mL micronized loratadine, an antihistamine, to be administered orally.
Zyrtec is found to be more potent, or stronger, in laboratory studies, compared with Claritin,” says Dr. Kung. “It also reaches a higher concentration in the skin, which can be more helpful for skin-related allergies. However, Zyrtec has a greater chance of making you sleepy while taking it.”
Some of the best oral antihistamines for dog allergies include Curist Allergy Relief (levocetirizine), fexofenadine (brand Allegra), and cetirizine (brand Zyrtec), which can help reduce your sneezing and itching.
Loratadine comes as 10mg tablets and as a liquid medicine (labelled either 5mg/5ml or 1mg/1ml). The usual dose in adults is 10mg once a day. Doses are usually lower for people with liver problems.

Q. My dog is a lab. 12 years old and in great health. He has started to lick and swallow pebbles in my back patio area. Can you give me advise. I juse
ANSWER : A. There are two theories one being the dog is lacking minerals and the other is behavioral some dogs will lick and swallow rocks when they’re bored or anxious. So what do you do? Start by ruling out something medical by having him examined by your vet. If its determined he’s healthy and it might be behavioral then you can address the behavioral issue by giving the dog more attention, exercise, etc I would be more than happy to trouble shoot this issue with you through a private consult.

Until you determine what the cause is I would not leave your dog unsupervised where he can ingest pebbles or other foreign objects. If you must leave the house you can consider kenneling (if you’re not already doing so), When you’re out for a walk or break keep a close eye that he does not ingest rocks, ingesting them is very dangerous and might require surgery to remove them.

This type of issue is best addressed through a private consult. There can be several other reasons why your dog is eating pebbles,what I wrote above is just the most common (not saying they apply to your dog) a private consult we will do a Q&A and get to the bottom of this.

Q. How much should I feed my cat?
ANSWER : A. How much a cat should eat depends on many variables including his activity level, metabolic rate and the food you are offering. Use the feeding guide on the cat food label as a starting point. These instructions usually read something like, “for cats weighing 5 lbs, feed between 1/2 and 3/4 cup per day; for cat’s weighing 10 lbs, feed between 3/4 and 1 cup per day; and for cats weighing 15 lbs, feed between 1 cup and 1 1/2 cups per day”.

Use your cat’s body condition to fine tune the amount you offer. For example, if he is overweight offer an amount on the low end of the recommended range and reevaluate in a few weeks to a month. Your veterinarian can also help you determine how much of a particular food you should be offering.

Q. My dog has a large bladder stone. Is surgery necessary or can it be dissolved?

Q. What should a Papillon weigh that is 11 inches at the shoulder?
ANSWER : A. Per AKC breed standard, there is no set weight for the Papillon. The only guideline given is that weight should be proportionate to height. In general, females may weigh a bit less than males; yet in regard to height both genders will fall between the 8 to 11 inch guideline.

In general, if a Papillon is of standard height, the adult weight will be between 6 pounds (2.72 kg) to 10 pounds (4.53 kg). It is not uncommon for a female to be a bit smaller than a male in regard to weight. Females tend to settle down near the 6 to 8 pound range and males generally are a bit larger and are closer to the 9 or 10 pound range.

We have seen some sources list the weight of the Papillon to be as tiny as 4 pounds (1.81 kg) however this is not common and a Pappy of this size would be considered undersized should he or she be the expected 8 to 11 inches tall (floor to withers).

So, with this information, your dog should weigh about ten pounds if she is 11 inches at the shoulder.

ANSWER : A. It depends very much on the size and density of the bone and the size of the dog that swallowed it. Some bones will be small enough and dissolve enough to pass without incident but many large and stronger bones can become lodged and cause obstructions as they move through the gut. If he ate it very recently it may be worth discussing the size with your vet to see if they can remove it from his stomach before it causes an intestinal obstruction. Monitor very closely for any abdominal discomfort, colic or vomiting which would indicate a problem

ANSWER : A. It is best to not crush or attempt to alter medications unless instructed by your vet. If your dog is having trouble taking the meds, you can try hiding them in a soft food such as a piece of lean meat or cheese, or even a pill pocket. Capsules should not be opened as it can change the dosage of the medication. You can also try giving the pill manually and then squirting in a syringe full of water afterwards to get your dog to swallow the pill without having to try dissolving it in water.
