c＋＋中输出与输入不符的问题

#include
using namespace std;
class Dog
{
public:
int get(int x,int y);
int put();
private:
int age,weight;

};
int Dog::get(int x,int y)
{

age=x;
weight=y;

}
int Dog::put()
{
cout<<"age is :"<<age<<endl;
cout<<"weight is :"<<weight;
}
int main()
{
int x,y;
cin>>x>>y;
Dog a;
a.get(x,y);
cout<<a.put();
}

cout<<a.put(); -》a.put();
