Construction of Mobile Toilet for Black Dog

The construction of a mobile toilet for black dogs can choose from the following four plans, which should be flexibly adjusted according to the dog's size, budget, and usage scenario:

I. Customized Refrigerator Rack Plan

Materials and Cost: Select a reinforced refrigerator rack (frame size 54×42cm, vertical bar spacing 2.5cm), paired with a shallow box or breeding box (depth selected according to the dog's size), with a total cost of approximately 40 yuan.
Applicable Scenarios: Suitable for small to medium-sized dogs, such as Corgis and French Bulldogs.
Key Operation Points:

• Ensure the vertical bar spacing is sufficient for feces to fall through while preventing the dog's paws from getting stuck;
• If a deeper container is needed, it can be replaced with a breeding box, but note that the overall weight should not be too heavy for easy movement;
• Regularly clean the feces that fall through to keep the rack clean.

II. Ready-made Rack Combination Plan

Materials and Cost: Purchase a ready-made rack with dimensions of 44×29×8cm (compatible with a plate), and fix the movable feet with 502 glue and tape. The customization price is approximately 30-100 yuan (charged according to size).
Applicable Scenarios: Suitable for families with a limited budget who need quick construction.
Key Operation Points:

• Prioritize selecting racks made of metal or hard plastic to ensure load-bearing capacity;
• When fixing the movable feet, ensure they are thoroughly glued to prevent tipping during the dog's activities;
• The plate should have a leak-proof design to prevent urine spillage.

III. Customized Iron Rack Plan

Materials and Cost: Customize a 57×37cm iron rack (vertical bar design, edge distance 5cm, hole distance 1.8cm, long side heightened by 7cm), paired with an 11cm high box, suitable for small dogs like Malteses.
Applicable Scenarios: Suitable for puppies or small dogs that require long-term use.
Key Operation Points:

• The heightened vertical bar design prevents urine splashing and facilitates cleaning;
• As the dog grows, the iron rack size can be adjusted or a larger box can be replaced to fit;
• The edges of the iron rack should be polished smooth to avoid scratching the dog's skin.

IV. Logistics Box Modification Plan

Materials and Cost: Logistics box, rack, cat litter, and use round-head screws to fix the rack (avoid sharp-headed screws that could hurt the dog).
Applicable Scenarios: Suitable for large dogs or outdoor use scenarios.
Key Operation Points:

• The logistics box should be made of hard plastic to ensure load-bearing and leak-proof properties;
• The rack should completely cover the box opening, and the screws should be fixed away from the dog's activity area;
• During training, place the dog's used urine pad in the toilet to use the scent to assist in positioning;
• The cat litter should be changed regularly to prevent bacterial growth.

General Precautions

• Size Adaptation: All plans should be adjusted according to the dog's size to ensure that feces can fall through smoothly without being stepped on;
• Training Assistance: Retain the scent of the urine pad or use attractants to help the dog locate the toilet;
• Safety Accessories: When fixing the structure, prioritize using safe materials such as round-head screws and tape to avoid sharp edges.
