Pet's info: Dog | Miniature Schnauzer | Male | unneutered | 8 years and 1 month old | 14 lbs
my 8 year old intact male mini Schnauzer has been walking slow and reluctant to jump up or down onto or from the couch or bed the last day and a half. he's always very eager to go on long walks but that hasn't been the case. he can pee and poop normally. this morning I noticed that the area below his butt and his butt were twitching or contracting. He didn't seem to be sexually excited. he has had his prostate checked in the last year and it is enlarged. never had joint problems.

Poor guy. These symptoms aren’t very specific for one disease process or another but there may be some underlying arthritis going on causing general joint pain. Also the prostate is internal so you can’t see it from the outside; however you may be talking about his testicles, which I can see there in the picture. If he was sexually excited then his bulbourethral gland (just behind his penis) can enlarge and cause everything to twitch, including his testicles I would assume.
You can try giving him some joint supplement such as Dasuquin or Cosequin over the counter for the next few weeks to see if this makes a difference. However, if his condition doesn’t improve or worsens, it’s best to get Gizmo examined by your vet. The vet should do a rectal exam also since he is intact, just to make sure his prostate is normal size. It is common for small breed intact males to have an enlarged prostate, which can cause difficulty pooping and sometimes overall lethargy and illness.
I hope this was helpful and best wishes moving forward with Gizmo. Take care.
