Is there topical home remedy I can use for my dog's pain from a paw injury?

I would go and see the vet. Not just because of the pain, but to get some antibiotics. My dog has lost two toes to infections because of nail damage. The groomer we were seeing wasn’t cutting her nails properly and she’d hurt them and then spend a lot of time licking her toe. Getting rid of the infection was difficult and in the end she lost toes.

She currently has another infection in her front foot and is hopping around on three legs. She’s obviously just prone to this type of injury.

So, I really would get a vet to check it so you can try to avoid any more serious problems.

Neosporin and I also really like Tri-Care 3 way wound ointment for dogs and horses ( have both here ) you can find it at most feed stores and tack supply if you have ranch stores in your area.
Works well, has topical pain relieving properties, moisture repellent, fly repellent and anti-bacterial too and is less than $10.00 for a big tube. Most important is to get a cone on her so will quit licking. You may need to cone her and wrap the paw for a few days with the appropriate ointment.

Also what @Earthbound_Misfit said, an oral antibiotic might be a good idea too just to be extra safe about potential infection. A broken claw is a wick for bacteria from licking, the soil, grass, etc. Think having a cut on your foot and then walking everywhere barefoot cramming dirt and germs int0 the wound.

It can quickly become infected. Watch for swelling, which will be a cause of pain.

When this happened to our dog, we took her to the vet. She ended up with a cone of shame and antibiotics, which of course reduced the swelling, hence reducing the pain.

We’ve learned to keep her claws clipped closer now.

You’ll need to see a vet. My old dog lost one of her nails once, when we were out in the middle of nowhere. In the time it took for us to find her a vet (~ 12 hours), she got much worse. Her nail bed got infected and we were dealing with that injury for weeks.

They typically need antibiotics and pain meds – a dog’s nail is full of capillaries and nerves. You can assume that your dog is in a lot of pain even if she isn’t showing it. Give her a treat from me.

Please take your dog to the vet.

You can give your dog ½ aspirin to help ease the pain. But do see a vet.

½ aspirin? That dose should depend on the weight of the dog! It might be an overdose! Or under dose.

We have a German Shepherd. We give her one Iboprophen in a blue moon to help with her hip pain. It works really well for her, too.

Ibuprofen in dogs has a very narrow safety range – the risk of toxicity is high enough that we don’t encourage pet owners to use it. Ever. (And it’s deadly toxic to cats.)

Buffered aspirin can be used in dogs under the guidance of a veterinarian. Even at the correct dosage, in some dogs it can cause GI upset and even gastric ulceration.

Topical applications of lidocaine or neopsorin generally don’t hurt, but they also generally dont help. Most dogs will immediately lick it off.

Your veterinarian may opt to bandage the foot for a very limited amount of time, mostly to keep the area clean and to prevent the dog from licking. A wet wound with lots of blood flow (like a nail bed) is a great place to grow bacteria, and licking keeps it nice and moist and warm. But leaving it on too long will trap moisture and make a soggy, stinking (bacterial) mess. Please don’t bandage it yourself unless you are experienced – a too tight bandage can cut off blood flow and have serious consequences. If the dog doesn’t tolerate a bandage, an e-collar may be necessary.

Since the foot is just about as contaminated an area as you can get, antibiotics are warranted. It may heal fine on its own, but why risk it?

I had a 60 lb. German Shepherd that I would give 1 adult aspirin to when he got old and achy.

Doc suggested baby asprin.
