Inflatable Collars

While wearing the Zen Collar, pets are able to eat, sleep and play at ease while staying protected. The Inflatable Collar is held in place by inserting the pet's everyday collar through the Zen Collar’s three inner rings. The velcro strap should be placed at the back of the neck and then adjusted for a perfect fit. The Zen Collar is a great alternative to the traditional E-Collar

The Zen Collar has an inflatable inner bladder made of a plastic vinyl that is inflated through a two-way air valve much like a beach ball. Once inflated, the size and thickness of the Zen function as a soft deterent. The inner bladder is protected by a pliable plastic outer jacket lined with a durable canvas material to resist bites and scratches. 

Securing Directions

  • To secure the Inflatable Collar in place: 
  • Make sure that your pet's everyday collar goes through the inner ring straps of the Zen Collar. Securely fasten pet's everyday collar. Inflate Zen Collar via air valve (do not use a compressor).
  • Connect Velcro strap on the ProCollar.
  • For larger breeds with longer limbs, or breeds in between sizes, always size up.
  • Always monitor a pet post-surgery to ensure collar is working properly. Some pets may be able to manoeuvre around any collar. 

Dog Boots

How to Measure for Dog Boots
To measure the width of your dog’s foot, place the foot on a piece of paper and press down on the top of the foot, mimicking how the foot spreads when the dog’s walking.
Mark the left and the right side of the foot on the paper and measure the distance between the marks.
Compare this to the boot sizes. The width of the foot should be smaller than the boot size.

For example, if the foot width is 3.75cm, order an XSmall at 4.5cm.

  • Fully open the two closures, squeeze the top of the boot into an “O” shape and slip paw all the way into boot with the hook portion at the front. 
  • Tighten lower closure first, then the top. Tuck your dog’s dew claw into boot, if necessary. 
  • Check boots periodically, retighten if needed. 
  • Remember to keep your dog’s nails short so they don’t puncture the material.
  • Go slowly, and put on one boot at a time. 
  • Don’t worry – your dog may be unsure and even “dance” when the boots first go on.

Tip:  Create positive reinforcement by using doggie treats to reward your dog along the way.  Immediately engage in a fun activity and your dog will quickly forget he/she is even wearing boots.

Take this measurement and check the circumference ranges below for correct sizing:

How to Measure for Wound Boots.

Use a soft tape measure and position it around the bulkiest/widest area of the bandaged paw.  If wearing a bandage, wrap or cast, a measurement of the circumference of the paw may help with proper sizing.

Boot Care
To wash, wrap the closures around the boot and wash in cold water, delicate cycle. Hang to dry.

 Collars & Harnesses


Since sizes within the same breed can vary dramatically, we are not able to tell you what size your pet wears. So measure well using sizing guidelines: 

Note: for Sighthounds such as the Greyhound and some other long necked breeds,  the collar is worn much higher, actually at the top of the neck below the head, but in measuring for coats and similar garments, the neck measurement for these dogs is taken lower than the collar, about midway between collar level and withers.

For dogs with short thick necks, such as Pugs, and dogs with a very full coat in the neck/chest area like Pomeranians, determining the neck measurement can be a bit tricky.

For most apparel, and neckwear accessories like bandannas on this type of dog, you may want to use a neck measurement taken a bit lower than collar level (closer to the withers) for a more flattering fit.
