Julia and Caesar acted like little babies there!hehehe  They did just fine, however the heartworm pills are different now. They used to give intercepter(sp?) today they gave me IVERHART MAX. I've never heard of this...do any of you use this?

Oh, also looks like I have a couple of chubby ratties!! Caesar has gained almost 3lbs in one year!!! My gosh!!! He weighs 18.5 now...and Julia weighs 16.5. She gained 1.5 lbs. I guess it was a long winter!!! Well, my vet said to cut back on the amout of food they eat and more walks...I do take them for walks but only about 3 times a week.  I'll have to start walking them daily!! I feed Natural Balance and I feed the amount is says to on the label..guess I'll be cuting back.

Which type of NB are you feeding?  From what I saw,  feeding the recommended amount would be too many calories for your sized dogs.  Their website says a 15 pound dog should get a cup a day, which is 485 calories (regular Nat Bal formula).  They probably should get a little less than 2/3 cup.  If you're feeding a cup a day, I would start giving 3/4 cups a day and maybe add a bit of green beans for added lo cal bulk.  Depending on their level of exercise, you could slowly cut back closer to the 2/3 cup level.

My vet said that Iverhart is the generic version of Heartguard.  I've been using Iverhart Plus, and give it from about June 1st thru November 1st. 

Well,  if you think they'll lose the excess weight over the summer thru exercise then that's your call.   You could always try cutting back a little over the winter months.  Or replace a bit of kibble with eggs or lean meat for added protein.   I don't mind seeing my dogs act hungry when I know they are getting what they need.  I fed EVO Reduced Fat mostly during the colder weather as Lucky seems to respond well to low carb (grainless) foods.  Now that it's warmer, they've been getting a couple of varieties of Eagle Pack Holistic foods, Chicken/Rice and Small and Mini Breed Adult .  I just know from experience that the weight can build without you really noticing until there's a problem.  Do your two still have a waist when viewed from above?  Is the area behind the stomache still tucked up, or is it getting to be more of a straight line?
