Amulet of the Beast Warden

Wondrous item, Unique, Requires attunement by a dog spirit

Man's Beast Friend. You have advantage on Animal Handling checks. When a beast within 5 feet of you is targeted by an attack, you may force the attack to target you instead.

One with the Wildlife. This item has 6 charges and regains 1d6 of them on a long rest. You can cast the following spells using these charges: polymorph (yourself only, 3 charges), beast sense (1 charge), speak with animals (2 charges).

Eternal Companion. If your mount dies, its soul is kept in the amulet. You can resummon it by performing an hour-long ritual during a long rest. Attunement is not required for this feature.

Empowered Mount. When you attune to this item, you may attune a mount to it as well to grant it the following benefits. The ritual to resummon your mount can be performed on a short rest as well as a long rest. If your mount has fewer than 20 maximum hit points (before bonuses such as blessings), its max HP becomes 20. While you are mounted, if your mount's CR is 1/2 or lower, damage that doesn't kill it has no effect.
