It's a good start. But you're going to have to make some changes. Try writing down everything you want to say in the ad on paper. Cut them out, & try rearranging them to find the position you want them in. Look at a lot of other ads to get ideas. A lot of it is poorly written, ie: "leave a msg". ON my cell, not AT my cell, "super low dog dog training prices" (in the balloon near the dog) and the top heading is pretty bad. There are too many different fonts, sizes, & colors going on, it makes it difficult to read. I'd go for a more classy look, in greys, black & white with possibly one accent color (red?) I'd put a nice border around it, & I would use a different heading. "Have a dog? Want one?" is a little odd. It sounds like you are selling or giving away dogs. Something like "Professional Dog Training" (if you're an amateur, you could say "Experienced Dog Trainer") now available for: then list your services, using bullets in front of each one: Basic training, Behavioral problems, & finish your list. THEN, under that I'd put, "Additional services" & say "Dog walking, etc.
I would avoid using the word "troubles" & use "problems" in its place. Also, I'd be careful of how you use the terms "assistance, information, sources" since they all mean pretty much the same thing, but you don't say what type of assistance, info, or sources. It probably seems like I'm picking your ad apart, but it's constructive criticism that I hope will help you make a better ad. And it has a good start. It's just a little scattered & you need to focus it a little more so that it's direct, clean, & to the point... as well as pleasing to the eye. Good luck, let us know what the final product looks like!
