Date of intake:: 6/10/2026

Date of initial:: 6/11/2026

Summary:: timid, whale eyes, lifts lip and shows teeth but allowed for all handling and task with muzzle

BEHAVIOR DETERMINATION:: Level 4

Recommendations:: No children (under 13),No cats

Recommendations comments:: No children (under 13): We reccomend Rex be placed in an adult-only home at this time. No cats: We reccomend Rex is placed in a home without small animals due to him trying to chase squirrels and pigeons.

Potential challenges: : House soiling,Fearful/potential for defensive aggression,On-leash reactivity/barrier frustration,Strength/leash pulling,Low threshold for arousal

Potential challenges comments:: House soiling: In the prior home, Rex is noted to relieve himself outside during walks but may have indoor accidents a few times a week.This suggests partial house-training consistency and may benefit from increased structure, supervision, and reinforcement of appropriate elimination behaviors. Please see the handout on House soiling. Low threshold for arousal/Fearful/potential for defensive aggression: During Rex medical exam he is note to become timid, whale eyes, lifts lip and shows teeth but allowed for all handling and task with muzzle. During Rex's behavioral assessment, he will approach and smell the assessor and display a tight muzzle, tense body with high hackles and a high tail he is quickly moved away due to this. This pattern suggests underlying fear that may escalate defensively when he feels unsafe or pressured.Please see the handout on arousal and Fearful/potential for defensive aggression. Strength/leash pulling/On-leash reactivity: During a borough break, Rex was reported to become reactive to other large dogs and people running. He pulls hard on the leash towards other dog and shows body tension, but does not bark or growl.To manage Rex's strong pulling and reactivity toward large dogs and runners, use a front-clip harness for better control and begin reinforcing loose-leash walking with frequent rewards. Practice counterconditioning by rewarding calm behavior when he sees triggers at a safe distance. Gradually decrease that distance as he becomes more comfortable. Redirect his focus with cues like “watch me” and avoid high-traffic areas during early training stages. Please see handout on On-leash reactivity/barrier frustration.
