Nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly used to control pain and inflammation in dogs. NSAIDs help many dogs lead more comfortable lives, but these drugs should be used carefully because they all can cause side effects, some of which can be serious.
While there aren`t over-the-counter (OTC) pain meds for dogs, dogs can take veterinary NSAIDs. These have to be prescribed by a vet. Most human medications are toxic to dogs and can cause more harm than good. Talk to a veterinarian before giving your dog anything from your medicine cabinet.
Nonsteroidal anti-inflammatory drugs (NSAIDs for dogs): Relieve pain associated with surgeries and arthritis including swelling, stiffness, and joint pain. Both Metacam and Previcox fall under this class of medication.
It`s important never to give paracetamol to your dog unless your vet tells you to – it can be very dangerous if it`s given incorrectly.” Claire explains that you should always head to your vet for advice, including if your pup accidentally digests a painkiller.
The application of cold can significantly help reduce swelling and inflammation (a.k.a. irritation) in your dog. It relieves pain by reducing damage to muscles immediately after an injury, surgery or heavy exercise. In addition, cold therapy will decrease muscle spasms and lead to faster healing.
Many pain medications considered safe for people can be toxic or even fatal for dogs. Never give your dog aspirin, ibuprofen (Advil), acetaminophen (Tylenol), or any other medication designed for humans without first consulting your vet.
You can only give your dog pain medications specifically designed for canines and approved by the Food and Drug Administration (FDA). These drugs also have to be prescribed by a vet, since there are no FDA-approved OTC painkillers for dogs.
Hot and Cold Therapies

If your dog has a chronic condition like arthritis or hip dysplasia, use a heat pack on their joints for up to 20 minutes to relax the area. If they have an injury that`s caused the joint pain, try a cold pack briefly to help them recover.

Among the most common medications your vet might recommend for your pet`s pain are nonsteroidal anti-inflammatory drugs (or NSAIDs), which offer relief similar to your own Ibuprofen or Aleve. PetMD suggests these medications can help reduce pain, swelling, stiffness, and any joint discomfort he may be feeling.
If your dog has swelling associated with a sprain, bruise, or tendonitis, apply ice packs to the area for 15 minutes twice daily. Flowing water improves circulation, reduces swelling, and promotes healing. Place your dog in a tub and swirl water around the leg or spray the leg with a hose for 15 minutes twice daily.
The short answer is no. While your vet may prescribe aspirin to help your dog when they`re in pain, you should not give them the same medication you have in your cabinet. Medicines like ibuprofen and naproxen can be toxic to dogs, even in small doses.
Although relatively safe in humans, ibuprofen and other NSAIDs can be extremely harmful to dogs. Poisoning may happen when pets get into the owner`s medications. In some cases, owners may administer ibuprofen to treat their pet`s pain prior to consulting a veterinarian.
For dogs, ibuprofen can easily exceed toxic levels. Ibuprofen has a narrow margin of safety in dogs. Signs of toxicosis can occur when as little as half a 200 mg pill is given to a 25 pound dog. The most common cause of ibuprofen toxicity is a well-meaning owner trying to alleviate pain in his dog.
Hold the swollen part of the body above the level of the heart several times a day. Sometimes, raising the swollen area during sleep can be helpful. Massage. Stroking the affected area toward the heart using firm, but not painful, pressure might help move fluid out of that area.
Certain foods can help tamp down inflammation. They include fruits, vegetables, and healthy fats such as monounsaturated and omega-3 fatty acids, found in salmon and other fatty fish. Other good choices include dark chocolate, green tea, turmeric, and ginger.
Ibuprofen is toxic to dogs and you should never give it to your pup. Just three to six ibuprofen capsules can be deadly for dogs, so keep the medicine in a safe place. There are canine-specific pain relievers that you can get from your vet or try natural options.
The swelling occurs 30 minutes to a few hours after the exposure. A veterinarian will often give dogs with this reaction an antihistamine injection. Untreated, it may take a day or two for the swelling to subside.
An unspayed female dog`s vulva will become swollen as a part of her normal heat cycle, but it should return to its “normal” size after the heat is done (anywhere between 2-21 days is considered normal).
FDA-approved nonsteroidal anti-inflammatory drugs offer pain relief for many dogs with osteoarthritis. These drugs also help veterinarians effectively manage pain after surgery in both dogs and cats.
The medicine you have been given for your dog is called paracetamol, also known as acetaminophen. It may have a trade name such as Perfalgan, but often will just be called paracetamol.
It tends to get to work quickly and wear off within a couple of hours and only rarely cause side effects in Humans. Paracetamol is sometimes prescribed for your dog however the dosages will reflect the weight of your best friend. Giving a 500mg tablet to a Miniature Poodle for example, could cause ill effects.
If your dog has swelling, make an appointment with your veterinarian. The veterinarian will ask questions about his signs and any underlying conditions. The medical professional will do a complete examination and then recommend a urinalysis and blood tests.
Allergic reactions are the most common cause of facial swelling in dogs. Bee stings, medications, certain foods, vaccinations, exposure to toxins, pollen and bug bites are just some of the many potential allergens that may affect a dog if they present with a swollen face.

Q. Shiba Inu. He periodically shakes and trembles, usually unrpovoked and seeming for no reason. Usually cuddling helps but not always. Becomes reclusive
ANSWER : A. I do find that Shiba Inu’s are a really sensitive breed. I think the first thing to rule out is pain. That could be pain from a muscle injury or even gastrointestinal pain. Try to pinpoint whether it occurs after a meal or not. He might be painful due to something going on in his GI tract, and the pain is at its worse after he eats.

I’ve also seen a lot of small breeds like Shibas get back pain, and shaking can definitely accompany that as well. If you haven’t see your vet who can perform a good physical exam and look for any signs of muscular pain along the spine or elsewhere. It’s not a bad idea at this point to consider doing some blood work just to screen for any problems that could be affecting organ function, for example.

If he’s healthy otherwise, I think it’s likely that there’s something that’s scaring him at home. These things can be really difficult to identify, and you have to be really aware and note exactly when the shaking occurs, how long it lasts, etc, and look for patterns. Dogs can hear things we can’t, and he may be hearing things you’re missing, and the noise is disturbing to him. Cuddling is a good idea, also working to distract him and desensitize him with toys and treats might help. But like I said above – definitely rule out pain first.

Q. My 5 month old puppy has what feels like a fluid filled pocket on his shoulder , no visible bites or marks,
ANSWER : A. It is possible that an injury has caused swelling on the shoulder, or you are seeing blistering or even an abscess under the skin. Abscesses, or infections under the skin, may cause pain or feel warm when touched, or may ooze yellow or green debris. Swelling may also be warm or painful, or may cause discoloration or pain while walking. It is best to have the area examined by your local vet who will likely want to take a sample of the swelling to help determine the cause. Treatment depends on the underlying cause and may include drainage of the swelling, kennel rest, or medications to treat infection or pain.

Q. My 5 year old Dachshund has broken his rear leg. A trip to the vet is impossible for two more days (rural area), can I give him something for pain?
ANSWER : A. If your dog has a broken leg, then veterinary care is a must. If you can get into contact with your local vet before seeing him or her, they may be able to give you information on an OTC pain medication that could be safe to give dogs. Do not attempt to give any medications without first consulting your vet as many pain meds can cause kidney/liver failure or stomach ulceration if given to dogs. In the meantime, keep your dog on strict kennel or bed rest and only taking him out for short potty breaks is best to keep pain down and from letting the leg get further injured.

If by tomorrow you are still concerned, give your vet a call.

Q. Whenever I take my dog on walks he always barks at people and others dogs in my neighborhood. What should I do to resolve the problem
ANSWER : A. The very first thing to do is to make sure your dog is getting sufficient physical and mental exercise every day. A tired dog is a good, happy dog and one who is less likely to bark from boredom or frustration. Depending on his breed, age, and health, your dog may require several long walks as well as a good game of chasing the ball and playing with some interactive toys.

Figure out what he gets out of barking and remove it. Don’t give your dog the opportunity to continue the barking behavior.

Ignore your dog’s barking for as long as it takes him to stop. That means don’t give him attention at all while he’s barking. Your attention only rewards him for being noisy. Don’t talk to, don’t touch, or even look at him. When he finally quiets, even to take a breath, reward him with a treat. To be successful with this method, you must wait as long as it takes for him to stop barking. Yelling at him is the equivalent of barking with him.

Get your dog accustomed to whatever causes him to bark. Start with whatever makes him bark at a distance. It must be far enough away that he doesn’t bark when he sees it. Feed him lots of good treats. Move the stimulus a little closer (perhaps as little as a few inches or a few feet to start) and feed treats. If the stimulus moves out of sight, stop giving your dog treats. You want your dog to learn that the appearance of the stimulus leads to good things.

Teach your dog the ‘quiet’ command. Oddly, the first step is to teach your dog to bark on command. Give your dog the command to “speak,” wait for him to bark two or three times, and then stick a tasty treat in front of his nose. When he stops barking to sniff the treat, praise him and give him the treat. Repeat until he starts barking as soon as you say “speak.” Once your dog can reliably bark on command, teach him the “quiet” command. In a calm environment with no distractions, tell him to “speak.” When he starts barking, say “quiet” and stick a treat in front of his nose. Praise him for being quiet and give him the treat.

As in all training, always end training on a good note, even if it is just for obeying something very simple, like the ‘sit’ command. If you dog regresses in training, go back to the last thing he did successfully and reinforce that before moving on again. Keep sessions short, 15-20 minutes max, and do this several times a day.

Q. Can I give my 20 pound Cocker Spaniel something for pain until the veterinarian’s office opens?
