take/call the vet because I doubt that is normal when we got our dog fixed she didn't do that.
She may be in heat.
I would call the vet asap.
No, spaying removes the uterus.
WHAT????
Of course. Ask your vet.
You need to take the dog to the vet ASAP.
No but the dog can "think" it's i heat, it may go broken backed (humped even though it's fixed)
yes
No, he doesn't have testicles anymore and that is where the sperms are.
he should get fixed
Yes. I have a male dog who is fixed and everytime my female goes into heat, he mounts her and after a while, they become stuck together at which point, I intervene and keep them calm until they seperate.
no. if a dog is fixed they can never become unfixed.
Yes, they cut the dogs balls off... not his penis.
Trauma is normally the usual cause of dog nose bleeds or you could have just knocked a vessel in his nose, much like why humans have nose bleeds. Either way, I would advise you to be more careful with your dog from now on. If it happens again or any other worrying symptoms appear, go see a vet, it could be more serious if nose bleeds or other abnormal bleeding happen often. Another reason for nose bleeds can be Aspirin, so if you give your dog anything like this, I'd suggest stopping.
Sometimes when a dog is fixed, it doesnt get rid of all hormonal events 100%; but there is other reasons to.
