Beagle whining and shaking

Question
We have a 2.5yo male beagle. Hes not neutered. For the past 3-4 days he has been whining non stop. We take him for walks on a daily basis and he goes rollerblading with me 1-3 times a week.
So for the last few days the whining is nonstop like I said. And now he has started to shake. I don't really think there is anything wrong with him because he still plays with us and eats his food/treats as normal.
I'm hoping he is just looking for a female companion to get some stress out(in a sexy way).

Anyways I just wanted to get an experts opinion on the subject. Any thoughts? Thanks.

Answer
Hi, the whining and shaking is more related to a stress reaction, or medical issue, not a need for sex, he is either afraid of something or not feeling well. I would take him to the vet and have it checked out but you also didnt give me much detail on when and where he does it and what seems to happen when it starts or his actual behavior while doing it. It is hard to believe he is whining and shaking for 24 straight hours, if that is so, then he should have been taken to the vet days ago. If you would like to give me more detail about his normal habits and about how that has changed with this situation feel free to send me a followup to this question but I would still take him to the vet if it is still happening frequently
