Anal Furunculosis - Misty, July 2000

Misty, our 9 year old GSD bitch was taken to the Vet’s, as we had noticed two small holes by her anus, with an odorous discharge.


Various treatments were discussed and it was decided to put her on a course of a powerful antibiotic together with Hibitane wash. At the end of the course the discharge was gone but the cavities remained. Surgery was discussed, but as no guarantee could be given, and in view of Misty’s age, was decided against. In the meantime another small cavity had appeared. We had a choice, do nothing and have her put to sleep in the near future or try CYCLOSPORIN. I was warned of the expense and that it would be an unknown time-scale. The following is a time-table of Misty’s treatment.

24 July Antirobe x30mg 1 twice daily. Hibitane Wash 3 times daily.

3 August Discharge cleared but no improvement in cavities. Intrasite Gel 3 times daily.

5 August. Cyclosporin 100mg capsules 1 x twice daily. Diltiazem 60mg tablets half tablet twice daily (to aid absorption of Cyclosporin).

Synulux 250mg tablets 1 twice daily

Stop Hibitane but continue Intrasite Gel.

21 August Healing very slow – increase:-

Cylclosporin 1 x three times daily

Diltiazem half tablet x 3 times daily.

Synulux continue 1 twice daily.

Intrasite Gel continue 3 times daily.

31 August Cavities filling in inwards – outwards, continue medication as previous.

8 September On holiday but cavities virtually closed – hardly noticeable. Skin tone almost normal.

12 September Not quite 100% but well over 90% healed. Reduce Cyclosporin to one twice daily from

15 September Also Diltiazem, but discontinue Intrasite Gel after using up any remaining.

6 October Considered cured – discontinue all medication.
Enquired about maintenance dose, but Vet said he didn’t like to prescribe such a powerful drug on a permanent basis. However it was necessary to keep a close watch for any sign of re-occurrence.

Weight at start of treatment - 27kgs. Weight at end of treatment – 33kgs.

18 April 2001. To date there appears to be no sign of re-occurrence.

This may seem a rather lengthy discourse, but should your dog be diagnosed with Anal Furunculosis there is hope, if our experience is anything to go by.


Anal Furunculosis – Update on Misty.

Misty was considered cured of Anal Furunculosis on 6 Oct 2000 after treatment with Cyclosporin for a period of approximately 65 days. She was in an advanced stage when the treatment started on 24/7/00.

On 22 November 2001 a small fistula was noticed by the side of her anus. The Vet. Confirmed that it was the start of another bout of Anal Furnuculosis. There was no discharge and it was in its very first stage. Immediately started CYCLOSPORIN (1 x twice daily) and DILTIAZEM (half tablet twice daily), plus a course of antibiotics. Luckily we had some Cyclosporin capsules to hand from Misty’s previous treatment.

On 4th December back to the Vet’s. Fistula completely gone – treatment discontinued. Cyclcosporin is an expensive treatment. I cannot compare it with surgery as I have no idea how much surgery costs. The plus points – no discomfort for the dog – no anaesthetic – no period of aftercare etc. Misty suffered no side effects what so ever.

Misty went on to live for a further few years with no re-occurrence of A.F. If any of my other dogs ever develop Anal Furunculosis I would immediately go for the Cyclosporin treatment as against surgery. The treatment should start as soon as A.F. is diagnosed to ensure a more rapid recovery.
