My terrier harvests (fetches) ducks for me. It is definitely easier to grow and train your terrier when you have the entire amount in your gift box. As others have posted, in addition to getting them from your friends, you can also make treats and kibble in your Craftshop.

Only adult terriers can learn tricks. Tricks are sequential and require progressively more treats over consecutive days for each new trick ("Roll Over requires 1 treat per day for 1 consecutive day to learn; "Play Dead" requires 1 treat per day for 3 consecutive days to learn; etc... The last trick, "Fetch", requires 1 treat per day for 7 consecutive days to learn.)
