Puppy's red, saggy armpit rash not improving with Benadryl?

The spots where the rashes are definitely fit with seasonal environmental allergies. They may not have been there before, but would not be due to the Benadryl. It's more likely that it's a progression of the allergies and a sign that the Benadryl is not working well. Dogs tend to not be helped by certain antihistamines, but may be helped better by others. Luckily there are a few alternatives that can be bought over the counter. I recommend calling you veterinarian and asking if they could suggest another antihistamine. As long as they have no other concerns with Riley, they should be happy to give you an alternative. If the second antihistamine doesn't work and you still notice the rash/itching, then he will likely need a recheck exam and stronger medication. One thing you can do for the rash and itchy skin, is give a bath with cool water using an oatmeal or aloe shampoo. You can get these shampoos at the pet store. I hope that helps and Riley gets better soon.

These symptoms do sound likely that Nino has allergies. If it has been going on for weeks and is getting worse, he likely has seasonal/environmental allergies. Unfortunately over the counter allergy meds such as Benadryl don't work all that well, and he really needs something more effective to control his symptoms, which would need to come from a vet. The pimples you are seeing probably indicate a secondary skin infection which will need antibiotics to clear up. So, he will need a vet visit to improve. In the meantime you can keep those areas clean and dry; I recommend bathing him with a mild oatmeal based shampoo and drying him thoroughly. You can also wipe down his feet and muzzle with a damp cloth when he comes in for the night to get as much pollen, grass, and other allergens off him before he goes to bed. Hope this helps.

Minor rashes like this on Chloe are often due to allergies, which is why it responds to benedryl. You can continue to give the antihistamine which will help. Wiping her down with a wet wash cloth when she comes in from the outside will also help to remove allergens from the outside. Giving her a fatty acid supplement can also help to keep Chloe's skin healthier. Please post again if you have any further questions!

If you have tried to benadryl with no success, then Mabel will need a stronger medication to help with the rash, such as a steroid. Those can only be gotten from a vet. Since you have tried home remedies without success and she is getting worse, she does need to see a vet. I would take her into a vet today, as being very itchy will be quite uncomfortable for her.

The next thing to do is go to the veterinarian. If the antihistamines are not working, he may need something stronger. These lesions could also now be infected. Make sure to protect the area from rubbing or scratching and he should wear an elizabethan collar at all times. Have him examined soon.

Poor Riddick! Unfortunately, this looks like it is infected. You can try some benadryl and neosporin twice a day. See link below for benadryl dosing. I would not let him lick it. You can put a cone collar on him to prevent this. If he licks it, it will never heal. If you aren't seeing much improvement, I would have your vet take a look at him. Your vet will be able to start him on oral antibiotics and stronger allergy meds like steroids if needed. I hope this helps! https://www.petcoach.co/canigive/dog/benadryl

Thanks for using Petco Pet Education Center, formerly Petcoach! I cannot give a dose for Benadryl because I have not seen Doobie but I don't think you are giving him enough and often enough to help. If he has a rash, Benadryl may not be strong enough and he may also have a secondary infection and need antibiotics. I recommend taking him to a vet to see his skin and get antibiotics and possible steroids for the inflammation. Good luck and kisses to Doobie!
