Hi Jo, thanks so much for the rank! I'm really happy to know that you like it!
Since you said that you want to communicate a design that demonstrates "a fun and also a secure place to send your pet", I think this concept is works well with it.
The story behind the concept is : a dog playing with butterfly is represent that the dog is happy and having fun while roaming, surrounded by a nice environment to represent a secure place which makes the dog love to roam at roaming rovers!
If you have any other suggestion, please let me know. I'll do my best for you.
One thing that I forgot to added, I also made the dog jumping over the text which makes the dog and the text incorporated well. Let me know what you think.
