Hello Back again for more advice! I'm fretting at usual. Whilst we are at work our friend looks after Casey. Casey is always happy to arrive and seems to enjoy our friends dog's company. However recently they are playing a lot rougher - according to our friends partner who was surprised by how rough their dog was being with Casey. Not sure if it's because Casey is getting older (now 14mths, she's known him since she arrived with us at 6mths old) or if it's something that may be becoming an issue? There's about a 6kg weight difference, Casey is smaller but my friend says that she is the nippier of the two. Her own dog will wrestle, pin and mouth but not actually nip. I'm thinking Casey is nipping because she's being pinned? I'm also thinking that they may be spending too long together over a week? They do spend most days in the flat with only going outside for toilet breaks. Our friend does encourage them to take frequent naps throughout the day. What do you think? Am I worrying over nothing? I'm considering trying another daycare and splitting the week between there and my friend. We're not at the stage where we could leave Casey at home with a dog walker visit. So daycare is necessary. We've just got to the stage where either me or my husband can leave home without Casey becoming distressed. Haven't tried leaving her alone herself yet. But she can now stay in a room by herself for a few minutes. And will sometimes choose to sleep in the hallway with our door open on her own at night for a few hours.
