Potential challenges: : Resource guarding,Basic manners/poor impulse control,Mouthiness/poor bite inhibition,Handling/touch sensitivity,Fearful,Anxiety,On-leash reactivity/barrier frustration,Leash-biting,Strength/leash pulling,Low threshold for arousal,Bite history (human)

Potential challenges comments:: Resource guarding: Onix is note hover and body block over the dummy toy during his behavioral assessment. Training should focus on teaching “drop it” and “leave it,” using trade-up techniques, and avoiding direct confrontation over valued items. Reinforcing calm behavior during item-handling exercises can help reduce guarding responses.Please see the handout on Resource guarding. Basic manners/poor impulse control: Onix is noted to jump on the handlers often.Recommended strategies include reinforcing calm greetings, practicing “sit” as an alternative behavior, and rewarding four paws on the floor consistently to build better self-control. Please see the handout on Basic manners/poor impulse control. Mouthiness/poor bite inhibition: Onix is noted to take treats roughly. Recommended strategies include teaching gentle treat-taking by offering treats in a closed fist until he uses a softer mouth, reinforcing calm behavior before food delivery, and incorporating impulse-control exercises such as “wait” and “take it”. Please see the handout on Mouthiness/poor bite inhibition. Handling/touch sensitivity: It is noted that Onix will head whip and become uncomfortable when his collar is touched. Gradual desensitization to collar contact, pairing touch with high-value treats, and using cooperative care techniques can help him develop positive associations with being handled. Avoiding sudden grabs is important to prevent escalation. Please see the handout on Handling/touch sensitivity. Fearful/Anxiety: During Onix medical exam he is noted to After returning from eliminating he had high tail wag, investigated room, panting, whining. A little flinchy when attempting to touch. Placed muzzle for precaution, immediately attempted to remove, but able to examine with mild restraint. Patient removed own muzzle immediately after exam was completed. During his fist at a handling assessment he is noted to head whip when attempts were made to collar him. Once in the room he flinches, paces, and whines. Use gradual desensitization to handling and equipment, pairing each step with high-value rewards. Keep sessions short and positive, avoid sudden movements, and allow Onix to approach voluntarily to build trust. Please see the handout on the decompression period and generalized anxiety. Strength/leash pulling: Onix is noted to hard pull on the lead while on walks.Use a front-clip harness and reward loose-leash walking with frequent treats to encourage better leash manners. Please see the handout on Strength/leash pulling. Low threshold for arousal/Leash-biting: Oniox is noted to jump on handlers to grab onto the lead, he will display a flushed face and dilated having difficulty in settling down. Providing an appropriate alternative, such as a tug toy during transitions, and pausing movement when leash-biting occurs can help reduce the behavior over time. Please see the handout on Leash-biting.
