Liam has been having more frequent head tremors. he's had one or two a week for the last few weeks. the vet isn't concerned about it. but we are logging the episodes to see if we can find anything that might trigger the head tremors. our first boxer (r.i.p.) had head tremors all his life...so this isn't something that is strange to us. yet it still freaks us out a little each time it happens. we deal with it....yes. but that's not to say we enjoy it i remember reading a post somewhere about going grain free for dogs that experience head tremors. and, i was thinking about doing that to see if the tremors subsided at all. right now Liam is eating timberwolf organics lamb and apple. i was thinking about changing him to either the timberwolf Wild & Natural or the Ocean Blue since they are grainless. however, i'm concerned about the protein levels ( he is 15 months old ) has anyone seen a difference in head tremors by switching to grain free diet???? i mean........have they significantly decreased in frequency?? thanks for your input.
