The Definitive “Arthritis in Dogs” E-Book Free

“Arthritis in dogs” is a free online e-Book, bringing home the most important points I make with my clients as I counsel on mobility issues in older aging dogs.

The absolute most important issue in the management of mobility issues associated with aging and arthritis is the WEIGHT of the dog. I see dogs all the time that are at 70% carrying capacity under 130-150% load.

Fat dogs on crappy joints.

The Epic “Arthritis Triad” Approach to Canine Arthritis

I’m no genius but these three medicines work wonders on Arthritis in canines. I’m sure it’s because it intercepts three out of five of the common factors in canine arthritic symptoms. (I’ll pick all that in another article)

  • Here’s the three medicines
  • How they’re used
  • What we want to achieve
  • What we do with those results

Kidney Failure in Young(“ish”) Cats

Kidney Failure in Young(“ish”) Cats

When you get blood work back on a pet (Cat), it’s about nine years old and it shows kidney failure it’s not always clear what’s going on. There’s another test or two that you’d run on a dog and there are some tests you could run on a cat. Actually, there are ways to spend thousands. Or, treat the treatable? Give this a listen.

The above does not constitute advice or replace the necessary input of your regular veterinarian within the confines of a VCPR. The above is as much a ‘document’ for the benefit of a particular client I sent to this, as it is to others who may face the same situation.

A mask may be necessary. Racing muzzles are pretty easy to put on. There are lots of kinds of masks.

Some people are like “Nuts to this, I know she has a right to complain but I’m not getting bitten over this” and let their dogs go. Depending on the ‘battle’ it is, I could be aligned to that thought process.

But…. Continue reading Diabetes III Insulin for a Fractious Pet

Azo and Cranberries for Dogs

Folks sometimes call the office looking for something they can do for their dog til it can get seen, or over the weekend, or just IN CONJUNCTION with a standard treatment.

And they ask about AZO, AZO Standard. Which is FINE to ask about except it turns out, the compound in AZO STANDARD is toxic to dogs.

Azo Cranberry, on the other hand, can be soothing, and it makes it harder for bacteria and inflammation to occupy the bladder and urethra.

Currently, Azo Cranberry isn’t made with Xylitol (it’s been years since manufacturers used Xylitol in anything that was possibly going to be used for dogs and cats. They’ve gone to sorbitol for the most part but MAKE NO ASSUMPTIONS and look. Xylitol can be toxic to dogs.

These are Azo Cranberry gummie chews and perhaps they'd be better taken by pets? The tablets may be better suited to embedding in peanut butter, cheese or your favorite form of pill disguise. 

This is the tablet version. You can use "the adult dose" per 50 pounds of dog. That means if the 12 to adult dose is 2 tabs twice a day, go with that. If you're treating a little dog, consider quarters to halves. Still, the margin of safety on 'pure cranberry' is high. 
When treating dogs up to 120 pounds consider increasing the dose by 50% (Means 3 tabs instead of two)

I would add, that if some dog-breeder message board is running off telling people to use "just any" Azo, or they're recommending another Azo, (for example the one with the extra chemistry in it) AND you try it, AND it works and doesn't wreck your dog's kidneys or mentation, please let me know. That is COMMONLY a way I learn new things, is treating things the breeder message boards cause, SOMETIMES for better, SOMETIMES for worse.

Limbic Tumors (Melanoma)

The following is excerpted from one of my fave sites, (Vetfolio) for my notes category. (For future reference but linked for bibliographical accuracy.)

Limbal (Epibulbar)

Limbal melanomas are the most common ocular melanomas in dogs, accounting for 20% to 50% of these tumors,17-19 and are less common in cats.7 In both species, this tumor is typically a smooth, black or heavily pigmented, subconjunctival mass ( FIGURE 3 ) that is noted incidentally by an owner or a veterinarian.20,21 These tumors usually involve the adjacent cornea and/or conjunctiva and, much less commonly, may extend intraocularly.20,21 Differentiating a tumor of limbal origin from extension of an intraocular uveal tumor into the sclera may be difficult with advanced disease. Most canine limbal melanomas are located along the superior half of the limbus, and German shepherds appear to be affected more frequently than other breeds.17,19,22

These tumors are generally considered to be benign, and no cases of confirmed metastasis have been reported in dogs.17,19,21 However, subpopulations of cells within the tumor may display more malignant characteristics.21 The tumors tend to grow more rapidly in younger dogs and more slowly in older dogs and most affected cats.20,21 Limbal melanomas in cats are similar to those in dogs in appearance, treatment, and prognosis, although distant metastasis has been reported.7,20,23The recommended treatment of a limbal melanoma depends on the rate of tumor enlargement, extent of the tumor at presentation, and expertise of the surgeon or the possibility of referral to a specialist. Because of the benign nature of most of these tumors, small, slowly growing masses may be monitored for progression, particularly in older patients.1,21 For rapidly growing tumors, surgical resection (partial- or full-thickness sclerectomy/keratectomy) is potentially curative and may maintain a functional and cosmetic globe.19,24 Techniques for removing the mass and repairing the resultant corneoscleral defect are described elsewhere.25Additional treatment modalities have also been evaluated. Cautious application of strontium irradiation26 or Nd:YAG,17 diode, or carbon dioxide laser27 energy treatment alone or in addition to surgical debulking can be effective. Cryotherapy has also been reported as an effective component of the treatment of limbal melanomas.1,10,20 The relative success of cryosurgery in treating limbal melanomas has not been thoroughly evaluated. Enucleation can be curative but is recommended only in eyes in which the melanoma has invaded the anterior chamber, filtration angle, or uveal tract and painful intraocular disease (e.g., glaucoma, uveitis) has resulted. Determining the full extent of the tumor before surgery may require diagnostics (e.g., gonioscopy, high-resolution ultrasonography) typically performed by a specialist.
