Hello I am Dr. Joey. Thanks for trusting me to help you and your pet today. I am a licensed veterinarian with over 15 years of experience. I look forward to working with you.
This sounds quite concerning for Dude.
First, with the ear infection, he needs this reassessed by his vet. There is no over-the-counter miracle for this. It really just needs to be looked at again and his medications adjusted. HIs veterinarian must do an ear cytology (swab and look at what is in the ear in the microscope); I do hope this was done the first time. If rod-shaped bacteria was seen the first time, then it is possible this bacteria is resistant to medications and may need to be cultured at the lab to know what medication might clear this infection, or if the budget is tight your vet can prescribe a different medication with a different antibiotic (like using enrofloxacin, ofloaxin or tobramycin in the ear) instead of the gentamicin that is in most products. Or if this is still a bad yeast infection
, then a different anti fungal medication is warranted.
Next, please please stop the tea tree oil and witch hazel; I find in ears these products make it so much worse and hurts. For now, you should use an ear cleanser such as one your vet can prescribe (like epiotic) or a diluted vinegar water solution if you cannot get a different commercial ear cleanser (1 part vinegar to 4 parts water). This will NOT clear the infection but may help remove the other stuff (witch hazel and tea tree oil) from the ear.
Second, for his new pain, you are absolutely correct this could be spinal pain (back or neck). Neck is very possible from shaking his head from the infection. This is not something that you want to try to manage over-the-counter. This requires an exam by his veterinarian and serious prescription medication to help him improve. The stool softener (hope it was a product for dogs; do not use people medications as they can worsen the situation) if it was a fiber-based tablet is okay. But please know that constipation is very rare in dogs and if present is a symptom of dehydration. So, we must figure out why he is dehydrated. I would also ensure he is not straining due to diarrhea (they can look the same). The pumpkin is fine. The best thing you can do is encourage him to eat and increase his water intake. Talk to your vet about medication like lactulose (which is prescription) if your vet really thinks he is constipated. And I always recommend lab work in a truly constipated dog to screen for liver/kidney disease or other problem that can lead to dehydration since, again, this is usually a symptom of profound dehydration.
