However, hair constriction at the base of the penis is more common in long haired breeds (like shih tzus). Instead, what we have with our patient is an inflamed glans penis, possibly caused by bacterial infection. Due to its current swollen state, it is virtually impossible to maneuver the dog's penis back into the preputial cavity. Dipping it in ice cold dextrose solution did not help at all.
The Animal Doctor already instituted anti-biotic and anti-inflammatory treatment plus Nefrotec to brace our patient for a urinary tract infection lurking somewhere. Surgilube, a surgical lubricant containing a bactericidal gel called Chlorhexidine, is also proving to be very useful.
So far, our patient has good appetite and is being a good boy himself by not fiddling with his Paraphimosis. Catheter can pass through and urine is clear. Except for unsightly blood oozing from the inflamed organ, the dog does not seem to be in pain.
We hope this resolves in 3 days or less.
