When you get a Dachshund in your practice with monoparesis of one of his legs, send him to a clinic where they can perform a CT or MRI-scan to look for intervertebral disc herniation! This is a disease that can become a lot worse in a few days. Dogs with a disc herniation that just happened, have a pretty good prognosis when they can still walk a little. When the problem maintains however, it can become very worse in a few days. When the paresis becomes plegia, and the deep pain sensation starts to disappear, the prognosis of the dog becomes very reserved. Therefore, it is very important to intervene surgically as soon as possible!!! You can prevent euthanasia by acting fast, so don’t forget!!!

Other dog breeds to watch out for disc herniation are: 

  • Beagles
  • French Bulldogs
  • Welch Corgis
  • Basset dogs
  • Cocker Spaniels
  • Shih tzu’s
  • Lhasa Apso’s

Signs of disc herniation on CT or MRI-scans are:

  • Disc material in the spinal cord, visuable as mineralisation
  • Compression of the spinal cord 
  • Decrease of the intervertebral space

Here are 7 of my favourite veterinarian books. I highly recommend all of them. Reading (and looking at the pictures) is a great way of learning!

  1. Clinical Signs in Small Animal Medicine by Michael Schaer: There are a lot of pictures in this book, it is amazing. It is very interesting to look at the pictures and you learn a lot about how to recognize clinical signs.
  2. Breed predispositions to Disease in dogs and cats by Alex Gough and Alison Thomas: I searched for a book like this a long time. Differential diagnosis are very important in veterinary medicine and this book helps in finding which disease is more important in which animal breed.
  3. Common diseases of Companion Animals by Alleice Summers: This book gives all the most important diseases in the most important animals for a small animal veterinarian. It’s very complete and written in a very easy way, which makes it even more enjoyable to read.
  4. Clinical procedures in Small Animal Veterinary Practice by Victoria and  Richard Aspinall: This book shows everything about the veterinary procedures you have to know. It’s a very handy book and fun to read.
  5. Small Animal Medical Differential Diagnosis by Mark Thompson: This is a very small but unbelievably good book. It has everything you need to build the best differential diagnosis for any animal, based on its symptoms. It is the best!!
  6. Clinical Veterinary Advisor Dogs and Cats by Etienne Côté: This is a very heavyweight book and is enormous. But it caries éverything you have to know. You also get an account for the internet version of it, which is very useful. There are also other types of this book: Exotic Pets, The Horse,… in case you are more interested in these animals. (I also have the exotic pets-book and I adore it!)
  7. Mosby’s Veterinary PDQ by Margi Sirois: Back to a very small book with this one. Together with number 5, this is one of the most useful books to have with you during clinics.

Simple Radiographic Measurements

  • Kidney: Length can be 2.5-3.5 times the width of lumbal vertebrae 2 in dogs. In cats their length can be 2-3 times the width of L2.
  • Small intestines: In dogs their height shouldn’t be bigger than 1.6 times the height of L5. In cats they shouldn’t be bigger than 12 millimeter. If they are a little bit wider than this, there’s paralytic ileus. If they are a lot wider than this, there’s mechanic ileus.
  • Big intestines: They shouldn’t be bigger than 3 times the size of the small intestines. 
  • Mediastinum: Cranially it is measured in comparison with the vertebral column. In normal dogs, it should be around 2 times the vertebral column. In brachycephalic dogs 3 times and in cats 1 time.
  • Trachea: This can be looked at in different ways, but one of them is that the trachea should be around 20% of the chest entrance in normal dogs. Brachycephalic dogs need a 16% and Bulldogs only 12% to be considered ‘normal’.
  • Heart: There are a lot of important measurements possible for the heart. Vertebral heart size goes from 8.7 to 10.7 in dogs. Laterally the heart should be 2-3 intercostal spaces and vertically it can be uptill 75% of the thorax height. On the ventrodorsal view it has to be about 65% of the thorax width.

There are two main branches of vessels below the carpus in the equine lower limb. Between the metacarpal and the interoseus (suspensory ligament) is the lateral/medial metacarpal vessels (2). Between the suspensory ligament and the deep digital flexor tendon is the lateral/medial palmar vessels (this is the main artery to the digit and hoof)(1).

The medial/lateral palmar vessels continue axially where they split into the medial/lateral digital arteries just above the fetlock.  The digital arties travel over the abaxial surface of the seasmoids (where they are palpable and where digital pules are frequently taken) and continue into the hoof as they travel with each side of the suspensory ligament.  The lateral digital artery is joined by the metacarpal arteries above the seasmoid bones.

Gave the wonderful Meg Turney some advice on helping here deal with Smee after he got stung.

Good information for all pet owners: if your pet is stung and there is swelling, you should monitor them. If the swelling does not go down, take them to a vet as soon as you can. If reaching a vet must be prolonged, you can give your pet Benadryl to help counteract the sting. .5 mg of Benadryl per pound of animal.

Make sure you let the vet know that you gave them benadryl, how much, and when so they can properly treat your pet.

TREATMENT OF OBESITY

1. Psychological part. It is very very very important to make the owners of the dog understand that obesity is a very serious problem. It can cause cardiovascular problems, respiratory problems, diabetes mellitus, locomotoric problems, … It is very important that the obesity is stopped as soon as possible! Owners have to understand that treating the obesity is important to save the dog’s life! Dogs can lose up to 2% of their body weight per week, so it will take time to achieve the ideal weight. It is important that the owners stick with the diet, although it will take a lot of time!

2. Diet part.

  • The most important aspect of the diet to treat obesity is a low energy density. You can calculate how much energy the dog needs with this formula: ‘290kJ/day * MetabolicWeight’. The metabolic weight is calculated by ‘(ideal body weight)^(0.75). To be able to calculate the ideal weight of your animal, you need his Body Condition Score (see above) and Muscle Condition Score. Ideally your pet has a 4 or a 5 out of 9. For each number that is more or less than 4 or 5, you need to add or reduce 10% of his ideal weight. When you have the body weight of your animal, you can then calculate his ideal weight. 
  • The energy given to the dog should be given in high concentrations of proteins. This is very important!! It should be higher than 25-30% of the dry matter.
  • Fibres should also be very high. These make sure that the dog has a satisfied feeling and won’t be very hungry. Fibres should be more than 20% of the dry matter.
  • Fat should be reduced to 7-8% of the dry matter. 
  • Because the diet will be given for a long time, it is important that it is balanced correctly! Otherwise deficiencies will develop and this will only give extra problems you don’t need. L-carnitin, omega-3-fatty acids and omega-6-acids are always very important to check, especially because you’re reducing your fat concentrations.

3. Activity part. It is very important that dogs with obesity are stimulated to move as much as possible! Play with it, walk with it, it can save your dog’s life!! 

Uptill 40% of the dogs and cats have obesity! Don’t let it come this far with your pet, because this could cause fatal problems! Fat tissue is an endocrine organ and brings the body in a constant state of inflammation. Don’t kill your animal by overfeeding it, save him now!  

Fluorescein dye is applied to an eye whenever suspicion of a corneal ulcer or scratch is present. On normal corneal tissue the green dye is washed off, on ulcerated tissue the color remains. The first photo shows a cat’s ulcer on day 1, with all of that green being the ulcerated region. On day 3 significant improvement had occurred (the cornea regenerates quickly if there is no infection or further trauma) and by day 8 it was improved further. Treatment for simple ulcers is usually antibiotic ointment to avoid secondary infection and an e-collar to prevent the pet scratching or rubbing at the eye. Ulcers can be caused commonly by trauma and lack of tear production.
