The monthly cost of owning a Collie typically ranges from approximately ¥500 to ¥1000 (about $70 to $140 USD).

1. Initial expenses are higher, including vaccinations for puppies, shampoo, and the purchase of essential dog supplies. This can amount to around ¥500 (approximately $70 USD).

2. During their growth, a 15kg bag of dog food, costing about ¥200 (approximately $30 USD), is a good option. You can supplement this with coarse grains, vegetable puree, and boiled meat mixed in. This amount should last around 2 months.

3. Adequate calcium and nutritional supplements are crucial. Larger breeds particularly benefit from calcium for proper development. A bottle of 80 calcium tablets, priced at about ¥20 (approximately $3 USD) and administered at 3 tablets per day, can last for over two months. Combining this with joint supplements to aid calcium absorption and reduce joint pain from rapid growth would add around ¥50 (approximately $7 USD) to your bi-monthly expenses.

4. While you might be able to bathe your Collie yourself when they are young, grooming becomes more difficult as they grow. A typical bath and basic grooming session can cost about ¥50 (approximately $7 USD), whereas a full grooming package can reach ¥100 (approximately $14 USD).Related resource:Pet Training
