First off, I am very sorry that Boston was diagnosed with cancer. How horrible for you and him. Some cancers can be extremely painful, such as an osteosarcoma (bone cancer), and it could be causing him to continually lick his front legs. He could also be licking them due to an skin infection or allergies. The best thing to do for him is have him seen by a vet as soon as possible, especially if you are concerned he is in pain. He may benefit from pain medications if he is in pain, and unfortunately there are none you can get him OTC. Many human ones are toxic to dogs and can be fatal if given. The vet can diagnose what is causing him to lick his front legs continuously and how best to treat it. Again, I'm sorry about his diagnosis and I hope this helps!

My dog has a bald spot on his leg. He occasionally licks and itches it with his teeth, but doesn't act sick. Vet prescribed mupirocin and noivasan solution which didn't work. Tried keeping a cone to prevent licking- he couldn't lick it, but it still
It looks like a lick granuloma which can be secondary to itching, pain, boredom, stress, OCD. They are commonly treated with antibiotics, anti-inflammatory medications, and bandages or E-collar to prevent licking. If that doesn't work then anti-anxiety medications, like Prozac, can be prescribed to see if that helps.

My dog had cancer of the muscle it was taken out and a few month later a brown patch has appeared on the same leg it's scab like but there has been no wounds. He has now started limping and dragging his leg what is this Please help me
Poor Alfie. I would be concerned that the cancer may be starting to come back in that area. It could be affected his nerves in that leg which is causing him to limp or drag his leg. I would have your vet take a look at it to see if he can see or feel anything. Your vet may want to take some x-rays to see if there is any boney involvement. Your vet will also be able to prescribe him some appropriate pain meds to make him more comfortable. I do not recommend giving human pain meds as most are toxic to dogs. I hope this helps!

Bella always has licked her paws and sometimes front legs. I noticed tonight it was wet there from licking and checked and noticed a small pea sized lump on her front upper leg. It is redish and soft. I attached pictures that are zoomed in. She does
Anytime a new mass is noticed, I always recommend having it evaluated to see what it is and if anything needs to be done about it. Unfortunately, we can't tell anything about a mass by just looking at it. Your vet can perform a simple test called a fine needle aspirate where they use a small needle to collect some cells from the mass, then look at them under the microscope. They may even need to send the cells to the lab for a pathologist to examine them, so we know what the mass is. If it is benign, you might not need to do anything about the mass at all, but if they see cells that worry them, they might recommend removing the mass. Skin tumors that have hair growing from them are generally benign, but I always recommend having them checked just to be safe. Good luck! I hope that was helpful. Thanks for using Boop by Petco.

My puppy has this on his leg now and won’t stop crying and licking it He’s gotten a bath and we try to keep it wrap her pulls it it’s been about a day and half now
Thank you for submitting your question regarding Chop. I recommend that he sees his veterinarian. I cannot tell from the picture if there is a mass or a wound on his leg. His veterinarian will examine him and may shave the surrounding hair to better evaluate the area. Based on these results, treatment can be started to help him feel better. He may need oral antibiotics for a wound or surgery to remove a mass. In the meantime, place an E-collar on him to prevent any further trauma. This will be more effective than wrapping it. I hope this information helps!

My dog has this sore on his hind leg that refuses to heal. It started to heal ( 2nd picture) and now it has gotten worse again ( 3rd picture) is there anything I can do without going to the vet? And what do you think is the problem? He also has some
Thank you for submitting your question regarding Bogart. The only thing at home you can try is having him wear an E-collar. This will prevent any licking causing further damage from self trauma. It may allow the skin to heal. If this is unsuccessful though, he will need to see a veterinarian. The area could be a mass on his leg (benign or cancerous) or he could have what is known as a lick granuloma. I hope this information helps!

I’ve noticed Blu has been coughing a little more then usual, we have been taking more walks since everything. Also he has been licking his leg more. Is this normal should I be giving him something??
Hi and thanks for posting. Coughing can have a variety of causes- respiratory infections, allergies, bronchitis among others. Licking a leg may indicate an allergy or can be a sign of pain. I would recommend Blu see his veterinarian soon for an exam and further evaluation. Your vet may recommend x-rays to get a better look at his lungs and legs. He may need antibiotics, pain medication, or other medications depending on what the vet's diagnosis is. I hope this helps!

What does it mean when my dog keeps on licking and biting his front leg joints?
Licking and biting on the paws and legs is a classic sign of allergies so he may be suffering from an allergy. It could also be secondary to anxiety or possibly pain. The best thing would be to have your vet examine him to determine the cause and treat the problem. Once diagnosed, your vet can prescribe medications to treat.

Hello, my dog has been intensely licking himself all over his back leg area. He is a 12 year old shih tzu/pekingese mix. He has some hard warts all over his body, which we took him to a vet for who said they were not serious/cancerous, and we could l
It sounds like Charlie is itching if he's intensely licking his back leg area. This itching can be caused by fleas, mites, ringworm, or allergies. If he isn't up to date on his flea treatment, I can give you one for him. First, I would give him Capstar. It's a one time pill that starts killing fleas within 30 minutes. Then follow up with a spot on treatment, such as Advantage or Revolution. This is a treatment that has to be used once a month. You will also have to disinfect the environment. Wash his bedding in hot soapy water, and vacuum the furniture and carpet surfaces. You can use a spray to kill fleas in the house, such as Indorex, or a flea bomb would work well to kill the fleas in the home. If he is up to date on his flea treatment, I recommend taking him into the vet for an exam this weekend or on Monday. The vet can do blood tests, skin scrapings, and use a Wood's lamp to diagnose allergies, mites, and ringworm. Once the cause of the itching is found, the vet can pre

I have a 10 year old Great Dane and lately we noticed a later knot on his left front joint right above his paw.
Poor Diesel! Is he painful? You need to take him to your vet. In an older Great Dane, I am so sorry to tell you this but I would be most concerned about a possible bone tumor. Take him to your vet for an exam--they will likely recommend taking an X-ray. They can also prescribe some medication to help with pain. Don't hesitate to post again if you have any other questions.

My 10month great Dane is having ulcers (foda) on face and legs. Why?
It looks like he might have an allergic dermatitis and skin infection. It would be best to have your vet take a look at him to determine the best way to treat. Your vet can do a skin scrape, cytology, culture, or biopsy, if needed, to help diagnose. He may need an antibiotic, anti-inflammatory, and/or other medications to help treat. You could also bathe him with a medicated shampoo, like DOUXO® Chlorhexidine and see if that helps.
