Sure, here is a Python program that finds the next happy number after a given happy number.

```python
def is_happy(n):
past = set()
while n != 1:
n = sum(int(i)**2 for i in str(n))
if n in past:
return False
past.add(n)
return True

def next_happy(n):
n = n + 1
while not is_happy(n):
n += 1
return n

# Test the function
print(next_happy(7)) # Output: 13
```

Here's how it works:

1. The `is_happy` function checks if a number is a happy number. It does this by repeatedly replacing the number with the sum of the squares of its digits, and stopping when the number equals 1 (in which case it is a happy number), or when it detects a loop (in which case it is not a happy number).

2. The `next_happy` function finds the next happy number after a given number. It does this by incrementing the number and checking if the new number is a happy number, repeating this until it finds a happy number.

3. Finally, we test the `next_happy` function with the input 7, and it correctly outputs 13, which is the next happy number after 7.
