the reason im choosing small dogs to take care of was we had a medium dog , a boxer breed and with my size im afraid that a medium or big size dog will pull me down to the ground .i experience that with my boxer dog for 15 yrs. since then i decided to just get a 3 cats in my house which the other two are already deceased. i treated this animals like my babies and loved them unconditionally.my 3 cats are freely to sleep on my bed just like my child .our cats sats on my lap,my husbands and my sons lap.my previous dog eat a good natural dog food thats why i think he lives for 15 yrs.and i did the same with my cats.i treat them like a humans.sometimes my husband thinks that im a crazy women.But oh well if you loved them dont matter if they are a dog or a cat..
