Date of intake:: 8/25/2026

Summary:: Friendly

Date of initial:: 8/26/2026

Summary:: Loose wiggly body, allows all handling

ENERGY LEVEL:: We have no history on Atlas 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 addition to physical exercise, to positively direct their energy and enthusiasm.

BEHAVIOR DETERMINATION:: New Hope Only

Recommendations:: No young children (under 5),Recommend no dog parks,Place with a New Hope partner

Recommendations comments:: No young children (under 5): Due to poor impulse control, we recommend a home with no young children. No Dog Parks: Due to the possible bite incident, we recommend no trips to the dog park. We recommend placement with a New Hope rescue partner who is able to provide an experienced, adult-only foster home. Force-free, reward based training and/or consultation with a professional trainer/behaviorist is highly recommended.

Potential challenges: : Basic manners/poor impulse control,Multiple-bite history/risk of future aggression,Leash-biting,Low threshold for arousal,Bite history (human),Bite history (dog)

Potential challenges comments:: Basic Manners: Atlas has been observed to jump up on handlers in a social manner. 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. Bite History (Dog / Human): Please see bite history above for more details. Please see handout on Bite History and Potential for Future Aggression. Leash Biting/Arousal: Atlas has been observed to become aroused and chew through the leash. Afterwards Atlas began jumping up and mouthing the handler's arm, breaking skin. Positive reinforcement training should be used to teach Atlas to remain calm during arousing situations. If they begin to escalate, people should pause the interaction, and create distance from the trigger. Pattern games such as 1-2-3 treat and the cue “mat” can be used to reinforce calm behaviors. Please see handout on Arousal.
