Inheriting super interface from a concrete class? [duplicate]

Question

I remember in Java once the parent class implements the interface, then all child classes of the parent is now implicitly of type interface (becoming a "super" interface if you will).

public interface IAnimal
{
    // Empty
}


// Parent class
public abstract class Mammal : IAnimal
{
    public string Genus { get; set;}
    
    public string Species { get; set; }
}


public class Dog : Mammal // Dog should be of type IAnimal now?
{
    public string FurColor { get; set; }
}


// Some service class that returns a list of Dog objects
public List<Dog> GetMyDogs()
{
    // Build list using Dog class
}


// Consumer
List<IAnimal> animals = GetMyDogs(); // Throws Cannot implicitly convert type Dog to IAnimal

Is the same capability available in C#?
