Could my dog's fish diet cause her swollen snout and hairless spots?

Updated on September 23, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Female | spayed | 25 lbs

My Shibu/Ridgback had one side of her snout swollen when we took her to the vet he said she was stung by a bee and that some hairless spots were due to high exposure to pollen. He gave her a cortisol shot and put her on antibiotics and i started to give her Zyrtec daily. Her snout is not black and she has more hairless spots. She is on a fish based diet could that be the cause of the hairless patches and should I be concerned about her snout?

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. Without pictures it is difficult to say for sure what the cause is. I would recommend applying a topical antibiotic ointment such as Sentry wound ointment and apply twice daily until resolved. This can be found at your local Petco. If this does not help or it worsens, I would recommend having her examined by a veterinarian so that the most appropriate diagnostic and treatment recommendations can be made. I hope this helps guide you in the right direction. Please let me know if you have any other questions or concerns and I would be more than happy to help you further.

Why is my dog's swollen snout bloody and spreading to her legs?

Hello, thank you for using Petco Pet Education Center, formerly Petcoach. This actually looks pretty serious. It could be an allergic reaction of some kind, a bacterial or fungal infection, or an autoimmune disease. I really think you should take her to a vet for an exam. If it is starting in other locations on her body then then I would be very worried about this being an autoimmune disease (such as pemphigus). This is not something that you will be able to treat at home.

Why is my dog's snout suddenly swollen after a walk, no injury?

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question. This could be an allergic reaction is there is no sign of trauma. The concern here is that the swelling is spreading, and it could get big enough to obstruct her breathing. I think it's best to have her seen by a vet now to get this treated. I hope this helps.

Hello. That is a pretty nasty reaction/infection. I would definitely recommend antibiotics for a situation like this.

Why is my dog's face rash spreading and swollen after digging?

Thank you for using Petco Pet Education Center, formerly Petcoach! I can see that Brooke has a significant amount of redness and hair loss under her nose, chin, and around her lips. This can be caused by bacterial or fungal infections as well as allergic reactions. Unfortunately, some fungal infections such as ringworm can come from soil and be transmitted to people. I recommend having Brooke seen by a vet as soon as possible - she may need antibiotics to resolve the infection and itching. I hope this helps and that all is well!

My puppy's snout is swollen. Is it a bug bite or allergic reaction?

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Laika and for providing pictures, they are very helpful. I see what you mean about the swelling, it is quite pronounced! This could be from a bug bite or it could be an allergic reaction. Oftentimes Benadryl is not strong enough to treat these issues, and stronger drugs like steroids may be needed. The best thing to do for her is take her into a vet immediately to get this treated. I hope this helps!

My dog's head is swollen, warm, and tender. Is it an allergy or bite?

Thanks for using Petco Pet Education Center, formerly Petcoach! It is not possible to know what is exactly going on just based on a picture. This could be due to an infection or an allergic reaction for example. I would highly recommend that you have her evaluated by a veterinarian for further assessment and treatment. They would be able to check for these possibilities and treat accordingly. Good luck!
