Date of intake:: 12/28/2025

Summary:: Thrash, snapped at staff member, fearful

Date of initial:: 12/28/2025

Summary:: Timid, shaking, sedated

ENERGY LEVEL:: We have no history on Nuevo 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 the behaviors seen in the Care Centers, Nuevo should go to an adult only home. Recommend no dog parks: Due to the concerning behaviors that Nuevo has shown during playgroup (see DOG-DOG SUMMARY), we feel that Nuevo 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: : Resource guarding,Handling/touch sensitivity,Fearful/potential for defensive aggression,On-leash reactivity/barrier frustration,Leash-biting

Potential challenges comments:: Resource Guarding: Nuevo has been observed to become tense and move away while in the possession of a toy. Nothing should ever be taken directly out of Nuevo's mouth, and any time something is removed they should be rewarded with a high value treat or toy. Please see handout on Resource Guarding. Handling/touch sensitivity/Fearful/potential for defensive aggression: When staff attempt to walk Nuevo, he thrashes on leash and has escalated to snapping attempts to scan him. Nuevo is uncomfortable with certain handling. Positive reinforcement should be used to help him associate handling with things he likes such as treats and toys. Please see the handouts on Handling/touch sensitivity and Fearful/potential for defensive aggression. On Leash Reactivity: Nuevo has been observed to become tense and stare at other dogs while on leash with raised hackles. Nuevo will need positive reinforcement, reward based training to teach them to look at you rather than other dogs. We recommend a front clip harness to help manage this behavior. Please see handout on On Leash Reactivity and Barrier Frustration. Leash Biting: Nuevo has been observed to jump up and bite the leash in kennel. During one instance catching the handler's finger. We recommend walking them with a toy to dissuade them from grabbing the leash. Positive reinforcement, force-free training is advised to teach them to focus on you rather than grabbing the leash. Please see handout on Leash Manners.
