Lateania: training Animal Taming destroys the pet investment it depends on (every tame resets loyalty to 0)

The only way to earn Animal Taming xp is to successfully tame a beast, and every success runs:

p.pet = Some(Pet::new(species, 0));

in svc.rs::tame. That is a fresh companion at zero loyalty, i.e. pet level 1.

Because Pet::attack and Pet::max_hp are base + base*(level-1)/4 and PET_MAX_LEVEL is 10, a pet at level 1 is at ~31% of its fully-fed power, and returning it to level 10 costs 700 loyalty = 28 feeds at PET_FEED_COST 20g (560 gold), plus the time.

The consequence is that the two halves of the companion system actively fight each other. Training Taming toward the level-50 payoff means ~1,136 successful tames, and each one wipes whatever loyalty you had built. So for the entire duration of the grind you are running a level-1 companion, which is materially weaker than the fed Stable pet you gave up to start. There is also no way to decline a successful tame or to keep the previous companion - the old one is released automatically.

The same Pet::new(species, 0) call in buy_pet is clearly intentional (a purchased animal is new to you), so this is not a code defect. It is the interaction with taming-as-a-trade that reads badly: the skill's only training method is also the thing that destroys its own output.

Suggested fix: carry a fraction of loyalty across a tame, let a player train the skill without swapping companion (an 'approach and release' that grants xp but keeps the current pet), or bank loyalty per-species so re-taming a beast you have raised before restores its level.
