Thank you for showing us the classpath etc.

But where are those classes? In particular, where is the Dog class? Are you sure the context classes are in that .jar in the Apache directory? Are you sure they are in the classpath? You realise the javax.servlet package isn't part of JavaSE? You need JavaEE for it.

the dog class I have not yet coded.But I don't know how to solve this error what to do abt javaEE. I m using Macintosh.

[Campbell Ritchie]

I may not know either. Start by unzipping or exploring those jar files and seeing whether they contain the classes you are looking for.

Don't use abbreviations like abt for reasons explained here.

[Mudra desai]

so where can I find answer to this?

[Jeanne Boyarsky]

Is this really the path of the servlet jar on your machine? In particular, it looks like you are missing a leading slash.
Users/mudradesai/Downloads/apache-tomcat-8.5.15/lib/servlet-api.jar

Try running "ls Users/mudradesai/Downloads/apache-tomcat-8.5.15/lib/servlet-api.jar" from the directory you are running the javac command. If it doesn't work, there's the problem.
