Hey Tina! First off, I love the channel art you have! (really digging the banner!) It's simple yet cute!
There are not a ton of videos on your channel(understandable because it's new) so I had trouble finding things to really point out. (which is good too. lol)
From the videos I watched, I found them all enjoyable and I think your dog is really adorable!
The only think I can really think of to mention that would really ramp up the quality of your videos would be B-roll. I struggle with this immensely so I don't expect everyone else to do an amazing job in it either!
B-Roll is just a bunch of different angles or shots that you can throw in and it really gives the viewer a much more in depth experience.
I strongly encourage you to check out this video I found a few weeks back! Search "Rob and Jonas b-roll" on YouTube (it's the video with the frog thumbnail) They are completely unrelated to my channel, but offer great direction and help in the video making department!
Also can I ask what camera you use to film?
All in all, I love the concept of your channel and have subscribed because I'm excited to see where you go with it!
Good luck with your channel!
