My Pet World: Dog's Fungal Infection Best Treated as Early as Possible

By Steve Dale, Tribune Media Services on

Q: My German Shepherd was just diagnosed with blastomycosis, The vet is concerned and says he's not optimistic. Of course, we're very concerned. Any advice? -- S.H., Louisville, KY

A: Blastomycosis is a fungal infection caused by the organism blastomyces dermatitidis, which is commonly found in decaying wood and soil. When ground is stirred up by construction, dogs are more likely to be exposed to the spores which cause this illness. People can get this disease, too, but our noses aren't typically to the ground, so we aren't as prone. Studies show the most commonly affected dogs are larger, and live or play near fresh water. For whatever reason, generally younger dogs get blastomycosis, though it can infect dogs of any age.

The disease can cause damage to the lungs, eyes, skin and bones. Without treatment, Dr. Al Legendre says, a dog will die.

"The secret is to diagnose and treat early before serious disease, particularly lung involvement, results," says Legendre, a professor in the department of small animal clinical sciences at the University of Tennessee College of Veterinary Medicine, Knoxville. "We can lose 10 to 12 percent in the first week. Over half the dogs will be cured after the first course of treatment; most others after a second course."

The problem for many owners isn't the eventual effectiveness of Itraconazole (Sporanox), but the cost of the drug. Legendre says the cost for a German Shepherd-sized dog could exceed $25 a day, and treatment might last from 60 to 90 days or more.



Q: I adopted my domestic short hair cat as a stray. Sable was quite sick for the first few months as a young kitten. I had her spayed at 9 months and declawed (I know I'm awful). Since the surgery, she's become quite a biter. Every time something happens, like I go away on vacation, the biting gets worse. Sable is punishing me. Even her play involves biting. Can you help? -- M.L., Tampa, FL

A: Smart as we are, we're not cats. Often, when kittens are brought up by people, they never learn not to bite. If Sable had bitten another kitten in her litter or Mom, she would have learned her lesson instantly. Not being feline, we have a difficult time replicating that instant communication.

Certified cat behavior consultant Pam Johnson-Bennett, of Nashville, TN, host of "Psycho Kitty" on Discovery Channel in the UK, explains that the biting might increase when you're away because of a lack of stimulation while you're gone, or maybe anxiety plays a role -- not because Sable is punishing you.

"It's important to teach your cat what is appropriate for play, chase, pounce and bite," Johnson-Bennett says. "Play (with Sable) with a pole toy at least once a day. If you won't be home, offer a variety of toys. Do consider that cats -- while they are independent -- can get lonely."
