Summary:: Jumping up on handler

Date of initial:: 9/8/2025

Summary:: Tense body for exam

ENERGY LEVEL:: Marshmello 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 Marshmello.

BEHAVIOR DETERMINATION:: New Hope Only

Recommendations:: No children (under 13),Place with a New Hope partner

Recommendations comments:: No children (under 13): Due to on leash reactivity and resource guarding we recommend a home with no children. 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: : House soiling,Resource guarding,Basic manners/poor impulse control,Handling/touch sensitivity,Fearful,On-leash reactivity/barrier frustration,Low threshold for arousal

Potential challenges comments:: House Soiling: Marshmello's previous owner states that he will urinate in the home a few times a week. Accidents should never be punished as this will likely make the problem worse. Please see handout on House Soiling. Resource Guarding: Marshmello was observed to become tense and hover over a toy that was in his possession. Nothing should ever be taken directly out of Marshmello'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: Marshmello's previous owner states that he will jump up often. 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. Handling Sensitivity: Marshmello's previous owner states that he will become fearful when his paws are touched and when his collar is grabbed. Positive reinforcement, reward based training should be used to pair touch with good things such as food rewards in order to teach Marshmello to be more comfortable with this. Please see handout on Handling and Touch Sensitivity. Fearful: Marshmello's previous owner states that he is fearful when startled and when pushed off furniture. It should always be their choice to approach a new person or thing. Marshmello 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: Marshmello's previous owner states that he will lunge towards strangers that approach. During his stay he was observed to fixated on other dogs and pull towards them with a tense body. Marshmello will need positive reinforcement, reward based training to teach them to look at you rather than other people. We recommend a front clip harness to help manage this behavior. Please see handout on On Leash Reactivity and Barrier Frustration. Arousal: Marshemello have been obsvered to become over aroused and mount handlers. During one instance when the handler attempted to him off their leg Marshmello bit their leg, only catching their pants. Marshmello held onto the handlers pant until the handler exclaimed verbally. Marshmello then released their pants. Marshemello should be rewarded with treats when calm. If they escalate to jumping or mouthing, people should immediately walk away from and separate themselves from Marshmello. Please see handout on Arousal.
