Date of intake:: 12/18/2025

Summary:: Allowed all handling, loose and wiggly body

ENERGY LEVEL:: Obsidian is described as active and enthusiastic. They will need daily mental and physical activity to keep them 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. We recommend feeding with puzzle feeders and food-dispensing toys. And we recommend using force-free, reward-based training techniques for Obsidian.

BEHAVIOR DETERMINATION:: Level 4

Recommendations:: No children (under 13)

Recommendations comments:: No children (under 13): Due to fearful behavior and on leash reactivity we recommend a home with no children.

Potential challenges: : Resource guarding,Basic manners/poor impulse control,Fearful,On-leash reactivity/barrier frustration,Strength/leash pulling

Potential challenges comments:: Resource Guarding: Obsidian has been obsvered to become tense while having toys in her possession. Nothing should ever be taken directly out of Obsidian'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. Basic Manners: Obsidian's previous owner states that he will jump up often when excited. 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. Fearful: During intake Obsidian was initially obsvered to be fearful, however he warmed up quickly. They should never be forced to approach anything that they are uncomfortable with or submit to petting or handling. It should always be their choice to approach a new person or thing. Obsidian would do best in an initially calm and quiet home environment and should be given time to acclimate to their new surroundings. Please see handout on Decompression Period. On Leash Reactivity: Obsidian was returned from a trial adoption due to hard barking and lunging towards other dogs. Obsidian 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 Pulling: Obsidian's previous owner states that he will pull hard while on leash. It is recommended that they be walked on a front clip harness or head halter, which will help diminish their strength through leverage, and that they be trained using positive reinforcement, reward based training to not pull on leash. Please see handout on Leash Manners.
