Weekly Pet Quiz: Mast Cell Tumors, Hairballs and CBD Oil

1 Mast cells exist in all the tissues of your pet's body, but where are they found in the highest concentrations?

  • Heart
  • Brain
  • Hair
  • Skin

    Mast cells exist in all the tissues of your pet's body, but they are found in the highest concentrations in the skin, respiratory tract and gastrointestinal tract. Mast cells are very rich in histamine, which is a vasodilator that promotes blood flow to tissues, and also heparin, an anticoagulant that prevents blood from clotting too quickly. Both of these naturally occurring chemicals play a role in all allergic responses, nonallergenic skin disease, wound healing and tissue remodeling. They can also increase stomach acid production.

2 Although they're common, hairballs aren't a normal part of a feline's digestive process.

  • TRUE

    While hairballs in housecats are very common, you may be surprised to learn they aren't a normal part of a feline's digestive process.

3 What's the first step to training your dog?

  • Establish dominance
  • Offer treats
  • Gain trust

    The lead trainer/dog wizard is Marta Gacsi, Ph.D., an ethologist at Eotvos Lorand University in Budapest. Gacsi is a researcher and co-author of several studies on the canine brain. According to Gacsi, it's not really important that the dogs are well-trained, however, a very important prerequisite was that the dogs trusted their owners (and in this case, their trainer).

4 What breed often has severe intervertebral disc extrusion?

  • Dachshunds

    Intervertebral discs are cushioning pads of fibrocartilage that sit between most of the vertebra of the spinal column. The discs have an outer layer of tough fibrous tissue and a center that is more of a gel-like substance. They act as shock absorbers for the bones called vertebra in the spinal column. Acute IVDE, also referred to as Hansen Type I intervertebral disc disease (IVDD), involves an explosive release of the gel-like material inside one or more discs into the spinal canal above. The released material bruises and also compresses the spinal cord, resulting in loss of sensation in the legs and the inability to walk. The problem is most often seen in short-legged breeds like the Dachshund. Breeders who intentionally create dogs with exaggerated physical traits have contributed to the growing problem of spinal cord injuries in certain breeds. Learn more

5 What can CBD oil be used for in pets?

  • Treat warts
  • Reverses diabetes

    Veterinary researchers at Colorado State University are conducting clinical trials of CBD oil to treat both osteoarthritis and epilepsy in dogs. Researchers at Cornell have also just completed a study of CBD oil in the treatment of canine arthritis, and their results support anecdotal reports of CBD oil's benefits to decrease pain and increase mobility. And pet owners report success using CBD oil for anxiety and behavior disorders in dogs, as well as seizure disorders and pain management. Learn more
