My lap suffers from CONSTANT build up in his ears (especially the right one), and this leads to ear infections. I've used MANY Otic/enzyme/ear cleansers and solutions for him in the past and I've never had one that recommends 2-3 DAILY usage. This tells me the formula must be weak and makes it a HUGE pain to use because he HATES having things put in his ears.Also the lid has NO resistance at all and typically drips a lot.However, I have been using it on his latest ear irritation and after about 4 days regular use it is clearing up quite a bit.There are better brands - but although I got this one through vine, I believe it retails for much cheaper than its competitors so it might be worth a try, especially if your pup budget is tight.I have an 8 month Labradoodle. I swear, every time I give her a bath, she gets water in here ears and her ears smell for days and she shakes her ears like crazy. This is an ongoing issue. I clean her ears nearly everyday!I’ve been using this Ear Cleaner for apprx 3-4 days now! It has really helped eliminate the bad smell and has stopped her shaking her head so much.I feel like it is working well. I also have used some other home remedies that work well for us too. But, if your not about the home remedies, this product here is great and seems to do the same job, if not better!I highly recommend this!I just can't be fully sure though, because I can't quite get my cat to cooperate... I'm sure all you other cat owners out there know how that can be, right? Lol, but anyway, I can say that I did get what I expected to at least. Meaning, I got what the listing described. This might be kind of unusual to mention but, one thing I really like is that all of the information on the box, like the directions, is also on the bottle itself. And I mean everything, word for word. Except the expiration date I think, but that's it. And because of that, if you lose the box, or don't want to keep it around, then you can still find all of the information you'd need on the bottle itself!but I'm not sure it's doing anything. I've used it so many times on her ears but I can never tell a difference. I'm also never sure if it bothers her more after I put it in than not.I noticed something going on with my cat's ears about a build-up of wax and started using this on her ears. So far it has cleaned them out and she is doing so much better. I use this in conjunction with the wipes and she is back to being a happy kitty.It seems to work good on our dachshunds ears. I’ve never had to use it so many times a day though, but whatever it takes to clear their ears up. The price is also reasonable.It's quick, works well, and cats don't hate it that much.
