My dog keeps trying to mount my puppy.

[NorahsBatty]

My dog is one. Pup is 6 months.

I wanted my male dog to mature before I got his balls chopped as I read the lack of them during growth can cause issues, even cancer.
Vet recommended 1 year.

Which worked well with female dog still being a puppy.

He was booked in March but due to lockdown they cancelled.

I've called every vet in the area, non of them will do it.

They won't even give him the temporary castration injection.

I live in a very small house. Downstairs is 2 rooms, which cannot be seperated.

Hes constantly trying to mount her.

I don't think she's in season and he doesn't even look like he is aroused but it's stressing me out.

Any ideas when the vets will be able to do castration again??

Sperm can also live inside a bitch for up to a week, so if they do mate just prior to her season she could become pregnant. I checked that recently as my girl came into her first season ten days after being at the dog sitters with a male dog and I was concerned.

Dogs won't mate if the bitch is not actually in season or if she is at the beginning of her season (proestrus stage) which lasts generally from 10-14 days but can vary hugely. During this stage the bitch will usually spot bright red blood and the vulva will start to swell. Male dogs may show interest in her smell but she will not stand to be mated (and an experienced stud dog wouldn't attempt it yet).

Bitches are only receptive to being mated when they undergo the hormonal changes that bring on the estrus stage of the season. The vulva will be extremely soft and swollen and the discharge changes from red to a straw or light pinkish colour. Ovulation and egg ripening takes place during this estrus stage and the bitch will be receptive to being mated (or most will be, a minority never are). This stage generally lasts around 5 days. Once it is over the discharge becomes bloody again and the bitch will no longer be receptive to mating.

It's correct that the sperm can survive inside the bitch for up to a week though so if they mate just prior to or at the point of ovulation, the sperm can still fertilise the eggs once they ripen (around 48 hours post ovulation so that is peak fertility).

Due to not being able to exactly pinpoint when the hormonal changes and ovulation take place without carrying out testing, it's important to monitor and preferably keep separate unneutered dogs and bitches for the duration of the season to avoid 'accidents' when your back is turned. However in terms of mating/pregnancy there's no need to worry about a bitch being around an entire dog if she's not actually in season... Unless she has silent seasons but that's another discussion!

You could try Down Boy by CSJ. A dog breeder I know has had some success with it. You could get a kennel/run for during the day and keep them in seperate rooms at night?

Updated advice from the BVA, which I interpret to mean you could ask for the chemical castration. Do research, tho, I remember researching this option and being told that one of the options has an increased likelihood of potentially causing testicular tumours further down the line. www.bva.co.uk/media/3430/bva-guidance-for-veterinary-practices-on-covid19-from-14-april-2020-final.pdf

Remember (sorry if I’m teaching my granny to suck eggs) that if you go ahead with the physical castration, the dog can still tie/impregnate an entire bitch for some time after he’s been done.
