Do they still remove the testicles during a castration?

[Septemberintherain]

I feel stupid asking this question especially as I have had 3 male (castrated) dogs in my life but hear me out….
All of my previously, castrated dogs have not looked like they have testicles after the op, just the empty scrotum sack which seems to get flatter/smaller as they get older.
We now have a 2 year old rescue. He came to us via a rescue centre, 8 months ago. The rescue informed us that he had been castrated. As far as I was concerned that was the case, never doubted it as I know it is common practice amongst rescue centres to neuter dogs and cats.
Now, as much as we adore our rescue, he is quite hard work. He is super anxious, crazy at times, has lots of anxieties and displays anxious behaviours. We have put this all down to his bad past and have been working hard to help him and also have been working with a behavioural dog expert.
Although he is somewhat better we still have a long way to go and he still displays some mad behaviours and will hump things a lot of the time (I have put this down to anxiety and over excitement at times).
Yesterday, dh was checking the dogs underneath area for ticks as we had found one on him the other day and said he still has what feels like a normal scrotum with testicles - we can’t see it well with naked eye as he is super fluffy but dh says they are definitely there.
When dh mentioned this to his work colleague today he said his dog still has testicles even after a castration because apparently the vets now just cut the tubes similar to a human vasectomy!
Really? I’ve never heard of this - is this true? Can anyone enlighten me because everything I am reading online says that castrations still involve removal of the testicles and now I’m wondering if the rescue haven’t bothered to castrate him.

They still remove the testicles, at least in the UK.

Are you sure you aren't looking at the bulbus glands? Easy mistake to make.

As your dog is nervous, be wary of neutering him in the event it turned out he isn't neutered - it tends to make the nervousness worse.

OnTheHamsterWheelOfDoom I was pretty sure it was still a full removal. I’m pretty sure it’s not the bulbous gland we are looking at, it’s the scrotum it’s still full. I will have to book a vet appointment and get their advice, thanks.

Castration is by definition removal of the testicles. Vasectomy wouldn’t achieve the desired result in dogs because the testicles still produce the hormones, and it’s the hormones that produce the effects we want to get rid of. (Usually that is - maybe in some cases they want the dog hormonally the same and able to mate, but not able to sire puppies, in which case vasectomy would be appropriate).
It will be interesting to hear what your vet says.

As the pp have said.

However if your dog is showing anxiety and stress do not castrate him - if he does still have his balls.

My dogs have vasectomies ns still proudly walk around with their balls. I have found a lovely vet who no longer rolls her eyes when I come into the consultation room
