Yes, the other syringes work much better in regards to getting out the bubble. Just hope I'm getting the .75 unit correct. She is still high today. I tried her on the bonito flakes tonight and she loved them. I suppose those are more low-cal than canned tuna. I gave her a bit of tuna with the flakes on the side and she ate all of it. I'll have to gradually give her only the flakes at test and shot time.
