When did you switch from high chair to toddler table?

I just got my 18 month old a toddler table but I have concerns:

• will she try to stand on the chair?
• she’s already trying to push back on the table and I’m afraid the chair will flip back while she’s in it
• how do you handle the dogs not touching her food or climbing on the table

I’m stressed! lol

I switched because she had started aggressively rocking back-and-forth in her highchair and laughing, and I was scared it would tip over
