Date of intake:: 12/31/2025

Summary:: Allowed handling

Date of initial:: 1/2/2026

Summary:: Loose, wiggly, jumps on staff in a friendly manner

ENERGY LEVEL:: We have no history on Xylos so we cannot be certain of their behavior in a home environment. However, they will need daily mental and physical activity to stay engaged and exercised. We recommend long-lasting chews, food puzzles, and hide-and-seek games, in additional to physical exercise, to positively direct their energy and enthusiasm.

BEHAVIOR DETERMINATION:: Level 4

Recommendations:: No children (under 13),Recommend no dog parks

Recommendations comments:: No children (under 13): Due to mouthy behavior we recommend an adult only home. Recommend no dog parks: Due to the concerning behaviors that Xylos has shown during playgroup (see DOG-DOG SUMMARY), we feel that Xylos should not visit dog parks. The Behavior Department recommends that he be socialized in a more controlled setting until his behavior toward other dogs can be further addressed.

Potential challenges: : Basic manners/poor impulse control,Mouthiness/poor bite inhibition

Potential challenges comments:: Basic Manners: Xylos has been observed to jump up on familiar handlers with a loose body. It is recommended that default behaviors such as "Sit" and "Off" are reinforced to substitute any frustration and teach them to control their impulses instead of simply reacting; proper management is also advised. Force-free, reward-based training only is recommended. Please see handout on Basic Manners. Mouthiness: Xylos has been observed to mouth handlers with hard pressure and take treats with a very hard mouth. We recommend never playing with bare hands, always with a toy, and ending play or attention whenever Xylos puts teeth on skin. They should be rewarded with attention and treats when they stop and/or when they are seeking attention in alternate ways. Please see handout on Mouthiness.
