I'm getting my ball in just over a week and am just purchasing the last of his stuff so I'm all set up before he gets here. He'll be 4 weeks old wen I get him, which of these sizes for a water bowl is more appropriate?
12 x 10 cm: 16.6 x 16.4 x 10.2 cm
11 cm: 12.4 x 12 x 12 cm
8 cm: 12.6 x 12.2 x 12 cm
Thanks.
