EXPLAINERS (Not articles)

None of these resources are intended to advise or shape the treatment plan of any individual or individuals who are NOT 'face-to-face' customers of Dr Erik Johnson's because THAT would be stupid. If he's not your Vet then you can't call for clarification or even know whether the information APPLIES to your pet. You could be treating heart failure with Robitussin and then wouldn't YOU feel like an ass?

These are images (Not articles) which I send to my clients with illustrations and the most highlight of facts related to a diagnosis. Some of the explainers just illustrate a 'feature' or context. Here they are:

Best Brush Ever

This is the best brush on the planet. This is the one I use on Ajax and I *did* used to use a Furminator - used to recommend that but for Ajax, it kinda grated on his elbows and knees. This is smoother and it CLEANS itself with the push of the button on the back the tines retract and then you just remove the mat of hair. They're cheaper than you'd think, too!

Amazon has them click here.

Similasan (Where to Buy)

I've recommended Similasan Allergy Eye since I heard about it from a colleague more than ten years ago. It "can't hurt" an ulcer but it can really soothe conjunctivitis. Is it "as good as real medicine"? Rarely. But it helps a TON. Any pet-parent first aid kit... Similasan Allergy Eye.

When you cant't use a steroid on a corneal ulcer - this is what you include in treatment plans to diminish redness and inflammation without vasoconstrictors.

Something else I found for my dog "Ajax" that's cool:

Sporn Dog Halter STOPS "pulling and tugging" NOW. (Link)

This is what I use now, with my dog Ajax. I used to use the Gentle Leader, but I didn't like including his face in the thing. Now, this just goes around his chest and he DOES NOT PULL ANY MORE. It's great! Amazon.com has it.

You can buy a fat bundle of 'wet wipes' with Cetaphil and I'd recommend it. They're great for cleaning healing wounds, dirty ears, cleansing around some eyes, under-tails, surgery sites, sores.

They are ALSO available right down the street at just about any store that sells makeup or cotton balls. So good.
